Description

The PS9702B is a highly integrated system-on-chip solution for multi-channel AV systems. It 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.
