[emagnioj]

Hello, on the eval I.MXRT1011 i enabled the S/PDIF receiver but it locks just up to 88.2 kHz 

How to lock spdif receiver at 96 kHz or 176.4 kHz

Thank you!

Hi,

Could you please provide how are you testing this to see if I can replicate this on my side? Please note input frequency range and implications.

Best regards,

Hello Felipe, I got an external S/PDIF TX and connected the output on pin 6 - GND of T1 (not present ) see schematic SPF-45852_c.pdf then jumped J35 and J36.

Then assigned SPDIF IN of the eval board at GPIO_10.

When i send music i see the locked bit asserted SPDIF-SRPC (Phase config register) and i can get back the music from SPDIF OUT pin 6 - gnd of T2 ( not present ).

At 96 kHz and more the SPDIF-SRPC reports no lock and i cannot get back music.

Thank you!
