CT7302 CT5302 audio SRC bridge

 CT7302 CT5302 audio SRC bridge        

General Description

The CT7302/CT5302 is a single chip dual channel audio digital to digital bridge with sample rate converter. 

The chip also provides System Management Bus 1.0 (also refer the I2C specification) for programming device function. 

In all system application, I2C configure is needed. Power on initial is mute.
