Introduction

The PS9702B is a highly integrated system-on-chip

solution for multi-channel AV systems. The PS9702B is 6

channel PCM to PWM modulator with sample rate

converter and pre-amplifier functions. It features six 24-bit

audio digital-to-digital converters and over-sampling digital

filters,

a sample rate converter, an audio DSP that

functions as an on-chip pre-amplifier with equalizer, volume

control, bass management, and compressor functions. The

PS9702B accepts industry-standard audio data formats

with 16- to 24-bit audio data. Sampling rates of up to 192

kHz are supported.
