Sadanori Kato

Hi,

Could you please give us your advice since we could not find TI device which can convert the TDM format to 4ch I2S format ?

Hi Kato,

We do not have a part that can convert TDM to 4 separate I2S channels, this will have to be done with a microelectronic or a processor/DSP.

Hi, how exactly looks your TDM format? Normal I2S support 2 channels. If you tell about 4 channel I2S that you mean I2S with two data wires?
For converting you can use some simple glue logic like many 74HCT164 for buffering or some preprogrammed Xilinx.
