C-Media High Performance PCI Audi o Controller

Oxygen^TMHD CMI8788 Datasheet v0.6

1. Features and General Description

1.1 Hardware Features

PCI 2.2 interface with bus mastering and burst modes

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

4 synchronous I²S input data stream pairs spread in 3 input DMA’s (for Dolby

pro-audio applications)

Optionally, a multi-channel AC-link can support 2 AC97 codecs

Programmable HW monitoring routing from I²S inputs to outputs

All I²S I/O pairs support 32-bit PCM data transfer and adjustable sample rate (up to

192KHz)

Integrated 192k/24-bit S/PDIF transmitter with 1 dedicated S/PDIF OUT DMA

Integrated 192k/24-bit S/PDIF receiver in recording DMA

S/PDIF IN supports digital loopback path for switching between optical and RCA

connections

48k/16-bit front panel DMA for AC97 codec

2-wire master serial bus or 4-wire SPI (Serial PeripheralInterface) bus to control

I²S codecs

2-wire slave serial bus to communicate with microcontroller unit (MCU)

Interrupt pin to inform external MCU to retrieve the data from the system driver

One MPU-401 MIDI UART port

EEPROM control interface

6 GPI phone jack detection pins

Advanced device-sensing technology indicates whether a speaker or a headphone

is plugged in the jack

9 direct-access GPIO pins

3 bonding-option bits for 8 identificationpossibilites

128-pin LQFP thin high-quality package
