I am developing an audio application on STM32F769I discovery kit and it require to process Audio sample from SPDIF RX and playback through on-board codec via SAI. Is the any example which demonstrate how to synchronize SPDIF RX with SAI transmitter on STM32F769I Discovery Kit?

Hello,
You can start from SPDIFRX example available under STM32Cube_FW_F7_V1.4.0\Projects\STM32F769I-Discovery\Examples\SPDIFRX\SPDIFRX_LoopbackRegards2016-10-03 12:23 AM
Hi,
Thanks for the info. Yes I've used the example as reference and developing an application. Initially SPDIF Rx and SAI Transmitter are in sync and suddenly they are out of sync. And after some time they become in sync and the sequence continues. For both SPDIF Rx and SAI, the input clock is PLLI2S. It seems there is a frequency drift on the SPDIF Rx.
