Functional Block Diagram The PanelLink TMDS core accepts as inputs the three TMDS differential data lines and the differential clock. The core senses the signals on the link and properly decodes them providing accurate pixel data. The core outputs the necessary sync signals (HSYNC, VSYNC), clock (ODCK), and a DE signal that goes high when the active region of the video is present. The SCDT signal is output when there is active video on the DVI link and the PLL in the TMDS has locked on to the video. SCDT can be used to trigger external circuitry, indicating that an active video signal is present or used to place the device in power down when no signal is present (by tying it to PDO#). The EXT_RES component is used for impedance matching.

Jitter measured with Clock Recovery Unit per DVI 1.0 Specification, Section 4.7 – Electrical Measurement Procedures. Measured with transmitter powered down. 2 All Standard Mode I C (100kHz and 400kHz) timing requirements are guaranteed by design. Control pulses include HSYNC, VSYNC, CTL1, CTL2 and CTL3. Pulses narrower than this minimum width specification are filtered out in the receiver and will not be seen at the output pins. ODCK duty cycle is independent of the differential input clock duty cycle and the transmitter IDCK duty cycle. DC and AC parameters specific to the operating mode of the SiI 1151 are listed on the following pages. The output pin timing specifications are dependent on the selection of output drive capability. Specifications are listed for two modes: SiI 151B mode, which requires no I2C initialization; and SiI 1151 mode, which allows for optimization of input data recovery and output drive using I2C programming. Designers should choose the mode most suited to their board-level requirements. 5 SiI-DS-0023-C SiI 1151 PanelLink Receiver Data Sheet Compatibility Mode Selection Specifications The SiI 1151 design provides new features that were not available on previous TMDS receiver series. To utilize the new features and ensure backwards compatibility, two mode selections have been defined. SiI 151B (Compatible) Mode: This mode allows drop-in replacement of SiI 151B and other pin-compatible receivers, and provides improved performance over other solutions. Strapping MODE (pin 99) = HIGH selects Compatible Mode. SiI 1151 (Programmable) Mode. Superior link recovery performance is possible, along with additional output drive timing margin, when this mode is selected. Strapping MODE (pin 99) = LOW and I2C_MODE# (pin 7) = LOW selects Programmable Mode. SiI 151B (Compatible) Mode DC Specifications The output drive strength is controlled with the ST pin as indicated in Figure 2.

This methodology provides a precise means of calculating setup and hold at any frequency and in any chip operating mode. CL indicates the load on the ODCK line. The load on the data/control line involved depends on CKST: for CKST=1, the control/data pin load is CL; for CKST=0, the load is 2x CL. Table 6.

For the SiI 1151 output pins, only the minimum output setup and hold times are critical. The SiI 1151 provides the OCK_INV feature, described on page 22, to allow external logic to decode data with either a rising or falling clock edge. OCK_INV=0 Case For OCK_INV=0, the worst-case setup time occurs when the clock to output delay is at a maximum (latest data) and the ODCK duty cycle is at a minimum (earliest falling edge). Conversely, the worst case hold time occurs when the clock to output delay is at a minimum (earliest next data) and the ODCK duty cycle is at a maximum (latest falling edge). This is shown in Figure 5. The falling active ODCK edge is shown with an arrowhead.

Receiver Output Setup and Hold Times – OCK_INV=0 Note: For Staggered Output timing in 2Pix/clk mode, refer to Figure 15.

Used to select between drop-in strap-selected operation, or registerprogrammable operation. To activate register-programmable operation, tie both pin 99 and pin 7 LOW. Refer to Selecting SiI 1151 (Programmable) Mode on page 31 for more details. HIGH=151B (Compatible) Mode – strap selections are used to set part operation. Internal registers controlling non strap-selectable functions are reset to their default values. LOW= SiI 1151 (Programmable) Mode – I2C registers are used to program part operation. In ODCK Polarity. A LOW level selects normal ODCK output. A HIGH level selects inverted ODCK output. All other output signals are unaffected by this pin. They will maintain the same timing no matter the setting of OCK_INV pin I2C Port Clock. When pins 99 and 7 are tied LOW, pin 100 functions as an I2C port input clock. The slave I2C function does not ever try to extend cycles by pulling this pin low, so the pin remains input-only at all times. Refer to Selecting SiI 1151 (Programmable) Mode on page 31 for more details. This pin accepts 3.3V signaling only; it is not 5V-tolerant. In Pixel Select. A LOW level indicates one pixel (up to 24-bits) per clock mode using QE[23:0]. A HIGH level indicates two pixels (up to 48-bits) per clock mode using QE[23:0] for first pixel and QO[23:0] for second pixel. In Staggered Output. A HIGH level selects normal simultaneous outputs on all odd and even data lines. A LOW level selects staggered output drive. This function is only available in two pixels per clock mode. 2 This pin must be tied LOW to put the receiver into I C mode. Refer to Selecting SiI 1151 (Programmable) Mode on page 31 for more details. Output Drive. A HIGH level selects HIGH output drive strength. A LOW level selects LOW output drive strength. I2C Port Data. When pins 99 and 7 are tied LOW, pin 3 functions as an I2C port data I/O signal. Refer to Selecting SiI 1151 (Programmable) Mode on page 31 for more details. This pin accepts 3.3V signaling only; it is not 5V-tolerant. The I2C address of the SiI 1151 is 0x76 HSYNC De-jitter. This pin enables/disables the HSYNC de-jitter function. To enable the HSYNC de-jitter function this pin should be HIGH. To disable the HSYNC de-jitter function this pin should be LOW. OCK_INV 100 SCL PIXS 4 STAG_OUT# 7 I2C_MODE# ST SDA 3 In/ Out HS_DJTR 1 In Power Management Pins Pin Name SCDT Pin # 8 Type Description Out Sync Detect. A HIGH level is outputted when DE is actively toggling indicating that the link is alive. A LOW level is outputted when DE is inactive, indicating the link is down. Can be connected to PDO# to power down the outputs when DE is not detected. The SCDT output itself, however, remains in the active mode at all times. In Output Driver Power Down (active LOW). A HIGH level indicates normal operation. A LOW level puts all the output drivers only (except SCDT and CTL1) into a high impedance (tri-state) mode. A weak internal pull-down device brings each output to ground. PDO# is a sub-set of the PD# description. The chip is not in power-down mode with this pin. SCDT and CTL1 are not tri-stated by this pin. I2C access to the registers is available when PDO#=0. In Power Down (active LOW). A HIGH level indicates normal operation. A LOW level indicates power down mode. During power down mode, all the output drivers are put into a high impedance (tri-state) mode. A weak internal pull-down device brings each output to ground. Additionally, all analog logic is powered down, and all inputs are disabled. Driving PD# LOW disables all internal logic and outputs, including SCDT and clock detect functions; it also resets all internal programmable registers to their default states. I2C access to the registers is disabled when PD#=0.

Pin 1 is used to enable or disable this circuit. Tying this pin high enables the HSYNC de-jitter circuitry while tying it low disables the circuitry. The HSYNC de-jitter circuitry operates normally with most VESA standard timings. In most modes, HSYNC and VSYNC total times and front and back porch times are multiples of four pixel times. If the timings are not a multiple of four, operation is not guaranteed and the HSYNC de-jitter circuitry should be turned off. When HSYNC de-jitter is enabled, the circuitry will introduce anywhere from 1 to 4 CLK delays in the HSYNC signal relative to the output data. Clock Detect Function The SiI 1151 includes a power saving feature: power down with clock detect circuit. The SiI 1151 will go into a low power mode when there is no video clock coming from the transmitter. In this mode, the entire chip is powered down except the clock detect circuitry. During this mode, digital I/O are set to a high impedance (tri-state) mode. The SCDT pin is driven LOW. A weak internal pull-down device brings each output to ground. The device power down and wake-up times are shown in Figure 11 and Figure 12. OCK_INV Function OCK_INV affects the phase of the clock output as indicated in Figure 18. The setting of OCK_INV is selected by a strap pin when in SiI 151B (Compatible) mode, and by a register bit when in SiI 1151 (Programmable) mode. OCK_INV does not change the timing for the internal data latching. As shown in the figure, the clock normally passes through two inverters, each with delay TINV. However, when OCK_INV is set to 1, the output clock only passes through a single inverter. This timing is described in the Calculating Setup and Hold Times section.

More detailed mapping information is found on the following pages. Refer to application note SiI-AN-0007 for DSTN applications. Note that the data configuration of the receiver is independent of the configuration of the transmitter. The data is always transmitted across the link in the same format, regardless of the selection of 12, 24 or 48 bit input format. Therefore, display-side designers do not need to know how the transmitter is configured. Receiver configuration is for compatibility with the display, not the transmitter. Table 9.

Designers should include provision for these circuits in their design, and adjust the specific passive component values according to the characterization results. Differences Between SiI 151B and SiI 1151 The RESERVED pin (pin 99) on the SiI 151B is required to be tied HIGH for normal operation. On the SiI 1151 part, pin 99 is defined so that tying it HIGH maintains pin compatibility with the SiI 151B. In this mode, the SiI 1611 chip meets all operational and timing specifications of the SiI 151B with these exceptions. Active mode power consumption is higher on the SiI 1151 part due to the new equalizer circuitry. Refer to Table 1 for actual values. TFSC is shorter and more predictable due to improved logic implementation. Selecting SiI 1151 (Programmable) Mode To use the programmable features of the SiI 1151 part: Tie pin 99 (the MODE signal) LOW Tie pin 7 (the I2C_MODE# signal) LOW The chipset registers are now accessible through standard I2C signaling up to 400kHz through pins 3 (SDA) and 100 (SCL). Note that these pins must be connected through pullups (2kΩ recommended) to 3.3V for correct operation. In this mode, several pins change their functionality from the SiI 151B standard as shown in Table 17. Table 17. New Pin Functions for SiI 1151 in Programmable Mode Pin 99 7 MODE tied HIGH Chip is in SiI 151B Compatible Mode STAG_OUT# MODE tied LOW Chip is in SiI 1151 I C Programmable Mode I2C_MODE# HIGH: Not Supported LOW: Chip is in I2C Programmable Mode SDA SCL 2 3 100 ST OCK_INV Programmable Mode Reset Recommendations For programmable mode operation, the SiI 1151 I2C logic must be reset at least once, at power-up time, for reliable operation. The reset is triggered whenever PD# (pin 2) transitions from LOW to HIGH after VCC has reached its nominal operating voltage. If the host controls PD#, this reset occurs automatically whenever the chip is brought from power-down mode to active mode. However, if the host is not controlling PD# and the pin is simply tied to VCC, there will not be sufficient time during initial voltage ramp to reset the logic. Figure 21 illustrates the timing requirement. V cc Internal gate turn-on voltage Internal I2 C RESET tRESET = 1 0 µ s min Figure 21. RESET Generation Delay 31 SiI-DS-0023-C SiI 1151 PanelLink Receiver Data Sheet Recommendation: Putting a 1000pF capacitor and a 10kΩ resistor on the PD# pin is sufficient to provide the needed reset delay. If the PD# is already controlled by external logic, that logic should be used to perform the reset function instead. Vcc 10kΩ Si I 1151 PD# 1000p F Figure 22. Recommended RESET Circuit For existing circuit designs where these methods are impractical to implement, other solutions may be possible. Contact your Silicon Image technical representative for information. Using SiI 1151 in Multiple-Input Applications Two SiI 1151 parts can be connected with their outputs in parallel to permit video from either of two independent DVI inputs to be recovered and sent to a single image processing device (such as a scaler). As an example of another application, one SiI 1151 part can be used with its outputs in parallel with an ADC to support a dual mode monitor. These applications may require the following considerations. Use the PDO# pin to disable the outputs from the SiI 1151 when it is not in use. The outputs will be tristated so that other devices can drive the lines. The chip engages internal pull-down resistors to prevent the outputs from floating, but these are very weak and will not adversely affect other devices driving the bus. Use the MODE pin to enable or disable the I2C interface from responding. All SiI 1151 parts in the system will use the same I2C address, so only one can be enabled for I2C access at a time. The PD# pin can be used in place of both PDO# and MODE. Its assertion will: disable the outputs from the SiI 1151; power down the internal SiI 1151 logic; and disable I2C access. Note: Asserting the PD# pin or toggling the MODE pin will reset the state of the registers to their default settings, so upon deassertion all special register settings will need to be rewritten. Using SiI 1151 to Replace TI TFP401 The SiI 1151 device pinout is very similar to that of the TI TFP401 receiver. Applications can immediately benefit from improved performance over the TI part, even if the programmability feature of the SiI 1151 device is not used. However, there are some areas that require attention when replacing the TI TFP401 part. When the staggered output mode is used, the TI TFP401 part times its DE signal to coincide with the first (ODD) data pixel. The SiI 1151 device times its DE signal to coincide with the first (EVEN) data pixel, one quarter clock period later. The SiI 1151 staggered output timing is provided on page.17. If the system has been designed to match the TI TFP401 timing noted above, it is often possible to adapt the SiI 1151 by using the OCK_INV, ST, and CKST selections to meet system timing requirements. This is possible because the SiI 1151 part has better timing characteristics in most applications. Contact your Silicon Image representative for additional application-specific suggestions. SiI-DS-0023-C 32 SiI 1151 PanelLink Receiver Data Sheet Adjusting Equalizer and Bandwidth The SiI 1151 provides access to several internal registers that can be set to optimize the connection to a variety of source devices and accommodate a range of cable lengths. The SiI 1151 provides access to several internal registers that can be set to optimize the connection to a variety of source devices and accommodate a range of cable lengths. Pins must be set in Programmable Mode according to the details shown in Table 17 on page 31. The rules for setting the registers for best operation are flexible; the only goal is to achieve best visual performance on the display. In general these guidelines apply. The EQ_DATA bits correspond to the cable length, with 0000 applying to the longest cables, and 1111 applying to the shortest cables. Cable quality and DVI signal source quality also factor into this setting, so there is no exact correspondence of settings to cable length. With good cable quality and a fully DVIcompliant source, cable lengths in excess of 20m are achievable at SXGA. The LBW bits correspond to the clock recovery PLL bandwidth. DVI-compliant transmitters are best accommodated by a setting of 4MHz as dictated by the DVI 1.0 spec. Recovery of data from non DVIcompliant transmitters is often better when the bandwidth is set to a higher value. Refer to Table 19 for setting information. Programmable Mode I2C Registers The internal registers are used as shown in Table 18. The I2C Device Address for SiI 1151 is 0x76. • The registers are set to their default values when the PD# pin is driven LOW (as well as when the MODE pin is set to HIGH). If the design does not provide a means of explicitly controlling the PD# signal, an RC circuit should be attached to the PD# pin to ensure that the I2C logic is reset properly at powerup.

Voltage Regulation using TL431 SiI-DS-0023-C 34 SiI 1151 PanelLink Receiver Data Sheet Decoupling and bypass capacitors are also involved with power supply connections, as described in detail in Figure 26. LM 317EM P Vin=5V Vin ADJ Vout 240 Ω 1% Vout=3.3V 390 Ω 1% Figure 24. Voltage Regulation using LM317 For the purposes of efficient power supply design, the relative power consumption of each of the power planes can be estimated as follows as a percentage of total chip power consumption. AVCC: 30-35% DVCC: 30-40% PVCC: 10-15% OVCC: 20-40% The power consumed by the OVCC power plane shows greater range than the others because of the variety of loading possibilities. PVCC is the power plane that is most sensitive to excessive noise, but noise on this plane can be controlled relatively easily due to the limited power consumed. Decoupling Capacitors Designers should include decoupling and bypass capacitors at each power pin in the layout. These are shown schematically in Figure 26. Place these components as closely as possible to the PanelLink device pins, and avoid routing through vias if possible, as shown in Figure 25, which is representative of the various types of power pins on the receiver.

Decoupling and Bypass Schematic The values shown in Table 20 are recommendations for noise suppression in the 1-2MHz range that should be adjusted according to the noise characteristics of the specific board-level design. Pins in one group (such as OVCC) may share L1 and C3, each pin having C1 and C2 placed as close to the pin as possible. This filter circuit should be placed on planes where power supply ripple could exceed the VCC noise specification. Table 20.

If the power supply is prone to generation of noise in this range in excess of the PVCCN specification, the component values shown in Table 21 should be used on the PVCC plane. Table 21.

Series resistors should be placed close to the output pins on the receiver chip, as shown in Figure 27. RX Figure 27. Receiver Output Series Damping Resistors SiI-DS-0023-C 36 SiI 1151 PanelLink Receiver Data Sheet Receiver Layout The receiver chip should be placed as close as possible to the input connector that carries the TMDS signals. For a system using the industry-standard DVI connector (see http://www.ddwg.org), the differential lines should be routed as directly as possible from connector to receiver. Differential pair length is not critical but ideally should be less than 10cm. PanelLink devices are tolerant of skews between differential pairs, so spiral skew compensation for path length differences is not required. However, each conductor of the differential pair should be routed together with equal trace lengths. Vias should be avoided, but if used they should be placed on both signal lines of the differential pair in a way that gives both lines equivalent reflection characteristics. Figure 28 illustrates acceptable routing practices for TMDS signals from a DVI connector, while Figure 29 shows an example of actual trace routing. 1: production Figure 30.
