CDB5366

In TDM mode, SDOUT_SEL1 and SDOUT_SEL 0 extract two stereo pairs from the CS5366 TDM stream,

convert the data to Left-Justified PCM format and send the data to the CS8406 data input pin.

0x00 TDM Pair 1 (Channel 1, 2)

0x01 TDM Pair 2 (Channel 3, 4)

0x10 TDM Pair 3 (Channel 5, 6)

0x11 Reserved

In PCM mode, SDOUT_SEL1 and SDOUT_SEL 0 select which SDOUT pin of the CS5366 is sent to the

CS8406.

0x00 SDOUT1 (Channel 1, 2)

0x01 SDOUT2 (Channel 3, 4)

0x10 SDOUT3 (Channel 5, 6)

0x11 Reserved

TDM2PCM/PCM selects the clock source for the CS8406.

0x00 8406 Clock Source is CS5366

0x01 8406 Clock Source is the FPGA TDM2PCM engine

4. CDB5366 HARDWARE
