Part Number: PCM1802

Hi team,

My customer use the PCM1802 in below schematic in the master mode.

But he cannot see the output clock in pin FSYNC,LRCK,SCKI,BCK,DOUT.

What may be the problem?

Thanks a lot!

Hi, Lacey,

Can you please share more details about the configuration of the device?, That is the setting on MODEx pins?. Also, one thing to note is that SCKI should be provided as this is the clock source for the device in Master mode, what is the clock frequency on SCKI?

Best Regards,
