LX21EVK01/NOPB

LX21EVK01 Channel Link III Ser/Des Evaluation Kit Rev 1.0 Oct, 2010 General Description The LX21EVK01 is designed to allow for easy evaluation of the DS92LX2121 and DS92LX2122 Channel Link III Ser/Des. This kit allows for 2 basic methods of evaluation: 1) Users may apply parallel clock, data and I2C commands, and evaluate the power, jitter and cable performance of the Ser/Des. Or, 2) Apply only a parallel clock and enable BIST mode. This allows the user to easily evaluate the serial link and check device feature functionality such as receive equalization, SSCG, etc. The LX16EVK01 boards uses USB connectors as the serial Channel Link III inputs/outputs. SMA connectors can also be attached and configured for serial input/output if other types of the cable are desired. Features • • • • • • • • • • • 20 – 50 MHz support for up to 800 Mbps (default configuration) LVCMOS parallel interface: 21-bit data (default) + clock + 2 upstream GPIO High speed forward channel + bi-directional control channel + back channel GPIO serialized to 1 pair AC Coupled STP Interconnect up to 10 meters in length Selectable receive equalization, SSCG, and deserializer output slew rate Integrated serial terminations @ Speed link BIST Mode and reporting pin I2C compatible Serial Control Bus Power down mode minimizes power dissipation Randomized, DC-balanced and Scrambled data stream with CRC >8 kV HBM Applications • • • Industrial Displays Machine Vision Medical Imaging Ordering Information PART: LX21EVK01 Demo boards: Tx: DS92LX2121-EVK Rx: DS92LX2122-EVK national.com © National Semiconductor Corporation 2009 1 Printed in U.S. Quick Start Guide: DS92LX2121 Tx Board: 1. Connect 3.3V DC power and ground of the board to JP12 from the power supply (3.3V on left pin, ground on right pin). Connect 1.8V DC power and ground of the board to the J5 and J6 from the power supply respectively. 2. Attach the USB cable to the TX board (DS92LX2121) output and to an RX board (DS92LX2122) input. 3. Attach parallel data and clock to the TX board at connector J1. This is typically done with a flat ribbon cable (not supplied). DS92LX2122 Rx Board 4. Connect 3.3V DC power and ground of the board to JP13 from the power supply (3.3V on left pin, ground on right pin). Connect 1.8V DC power and ground of the board to the J8 and J9 from the power supply respectively. 5. Attach the USB cable to the RX board (DS92LX2122) input from a TX board (DS92LX2121) output. 6. Attach parallel data and clock output to the RX board at connector J7. This is typically done with a flat ribbon cable (not supplied). Jumpers and switches on both the TX and RX boards have been configured at the factory; they should not require any changes for immediate operation. See the datasheet for more details. national.com © National Semiconductor Corporation 2009 2 Printed in U.S. Tx Board Configuration Settings Component Name Function Power Connections J8 5V DC J5 1.8V DC J6 VSS JP12 3.3V DC JP11 VDDIO Input and Output Connections 44 position wall header (DIN0 – DIN20, PCLK) J1 JP1 - JP4 Optional 5V DC Power Jack.
