Part Number: PCM2902C
Other Parts Discussed in Thread: TAS2780, , PCM2902, DIR9001

Goal: USB Audio & Audio amp.

Planning to use a PCM2902C SPDIF output into a TAS2780 (25W Class-D audio amp)

but the TAS2780 takes in a TDM signal while the PCM2902 outputs a SPDIF signal.

Suggestions?

Hi Michael,

The device you're looking for to interface between PCM290x and digital speaker amp is a SPDIF transceiver such as DIR9001 . This decodes SPDIF and provides clocks necessary for I2S.
