TAS5558 is designed to support DTS-HD specification Blu-ray HTiB applications. The ASRC consists of two separate modules which handle 4 channels each. Therefore, it is possible to support up to two different input sampling rates. Texas Instruments Power Stages are designed to work seamlessly with the TAS5558. The TAS5558 also provides a high-performance, differential output to drive an external, differential-input, analog headphone amplifier. The TAS5558 supports AD, BD, and ternary modulation operating at a 384-kHz switching rate for 48-, 96-, and 192-kHz data. The external crystal used must be 12.288 MHz. The TAS5558 also features power-supply-volume-control (PSVC), which improves dynamic range at lower power level and can be used as part of a Class G power supply when used with closed-loop PWM input power stages.

SDIN2 25 DI 5V Pulldown Serial-audio data bank 1 input 2 is one of the serial-data input ports and goes into the 1st SRC Bank. Four discrete (stereo) data formats and is capable of inputting data at 64 fS. 4 3.3-V master clock input. The input frequency of this clock can range from 2 MHz to 50 MHz. 5V Pullup 18k resistor to GND 5V Pullup Pullup Soft mute of outputs, active-low (muted signal = a logic low, normal operation = a logic high). The mute control provides a noiseless volume ramp to silence. Releasing mute provides a noiseless ramp to previous volume. Oscillator resistor (1% tolerance). Power down, active-low. PDN powers down all logic and stops all clocks whenever a logic low is applied. The I2C parameters are preserved through a power-down cycle, as long as RESET is not active. System reset input, active-low. A system reset is generated by applying a logic low to this terminal. RESET is an asynchronous control signal that restores the TAS5558 to its default conditions, sets the valid output low, and places the PWM in the hard-mute state (Non PWM Switching). Master volume is immediately set to full attenuation. On the release of RESET, if PDN is high, the system performs a 4- to 5-ms device initialization and sets the volume at mute.
