High Performance PCI Audio Processor

FEATURES

DESCRIPTION



PCI 2.2 interface with bus mastering and burst

The CMI8786 is a high quality PCI 32-bit

modes

multi-channel audio processor that can be built in

the home audio electronics or personal computer

to provide high fidelity sound and become a

professional audio processing center in your life. It

supports up to 10 outgoing channels and 4 ingoing

channels. The 10 outgoing channels are composed

of 2 playback DMA’s, which are multi-channel DMA

(24 bits, 8 channels, 96k), S/PDIF DMA (24 bits, 2

channels, 192k). The 4 ingoing channels are spread

in 2 recording DMA’s (24 bits, 96k), namely

recording A, B, DMA’s. The architecture of



Only one 24.576MHz oscillator is needed

4 synchronous I2S output data stream pairs

within 1 flexible output DMA



Programmable channel routing mechanism

among the 4 I2S output pairs

An alternatively multi-channel AC-link can

support 1 AC97 codec

Programmable HW monitoring routing from I2S

inputs to outputs.

All I2S I/O pairs support 24-bit high-definition

PCM data transfer and adjustable sample rate up

to 96KHz

recording is a unique point of CMI8786 that makes

the recording become the most flexible for the

users. The details of the recording mode selection

will be explained in the later sections.
