Hot selling Original stock sale CMI8788 High Performance PCI Audio Processo Chip LQFP128

Product Descriptions

The CMI8788 is compatible with all the popular codecs, from I2S codecs with over 120dB quality to the usual AC97 codecs. This ability gives customers 

the flexibility to design their products exactly the way they want them. The I2S, AC-Link, 2-wire master bus, and SPI interfaces are used to transfer audio data and control data between the CMI8788 and codecs. To facilitate the connection with existing home audio electronics, the CMI8788 has incorporated the S/PDIF transmitter and receiver with 192k sampling rate. An EEPROM interface is built for the CMI8788 in connection with the EEPROM to store and retrieve the non-evaporable data for customer applications, such as board configuration, sub-vendor and sub-system IDs of the PCI configuration, or any dynamic data that customers want to restore at the next power-on.
