PULSUS
PS9702B
6Ch, 24bit, 192kHz Digital Audio Processor
for Full Digital Amplifier
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.
