In an application with 2 RX, 3 TX digital channels, I am struggling to find an economical solution to convert the TDM inputs and outputs to I2S to interface with external components which do not support TDM. Effectively, I need to:
- Convert L, R I2S to TDM -> DSP
- Convert DSP L', R', Mic TDM to 2 separate I2S
The power consumption of the ADAU1761 make it the best (if not the only) choice for this application which must remain under 165mw in total, but the lack of multiple I2S channels is limiting. Does anyone have a recommendation?
