Digital Audio Processor Soc (Ps9829b)

8Ch, 24bit, 192kHz Digital Audio Processor for Full Digital Amplifier

"PS9818 UPGRADE VERSION"
The PS9829B is a highly integrated system-on-chip solution for multi-channel AV systems such as 5.1channels, 6.1channels
or 7.1channels. The PS9829B is 8channels and 3 additional channels PCM to PWM modulator with full 8channels sample rate converter and pre-amplifier functions.

It features 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 automatic gain limiting functions.

The sample rate converter is allowing for input of up to 96kHz, 8channels and 192kHz, 2channels. It automatically detects the sampling frequency and converts input sample rate to internal 192kHz sample rate. It makes easy for user to handle this chip. The PS9829B accepts industry-standard audio data formats with 16-bit to 24-bit audio data. Sampling rates of up to 192kHz are supported.
