PS9818
8Ch, 24bit, 192kHz Digital Audio Processor
for Full Digital Amplifier
Introduction
Features
The PS9818 is a highly integrated system-on-chip
General
solution for multi-channel AV systems such as 5.1 channel,
! 2 serial input ports for 8 Channel
6.1 channel or 7.1 channel. The PS9818 is 8 channel and 3
additional channel PCM to PWM modulator with full 8
! User can select the master/slave mode of input port
! Sub input port can be changed to serial output port
channel 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
! Supports 16/18/20/24 bit Input
! Supports 32kHz~192kHz Input Sample Rate
! I2C or SPI control bus
audio DSP that functions as an on-chip pre-amplifier with,
equalizer, volume control, bass management, and
! Internal PLL (low jitter)
! 100 pin QFP Package
automatic gain limiting functions.
! 2.5V core, 3.3V I/O Power Supply
The sample rate converter is allowing for input of upto
! 5V tolerant Inputs
96kHz, 8 channel and 192kHz, 2 channel. 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 PS9818 accepts industry-standard audio data
formats with 16- to 24-bit audio data. Sampling rates of up
Sample-rate-converter Section
