Description

DI2S is a universal solution which provides an interface between a microprocessor and I2S, left/right justified modes, PCM, TDM audio protocol codec. Thanks to flexible configuration it can work as a receiver, transmitter in master or slave mode, with configurable channel length or sample size. Additionally, number of audio blocks can be adjusted according to specific project needs.
