I would like to confirm the below two points.

1. The back channel frequency is 5.5MHz. Is it correct?

2. Are there any sources of around 30MHz inside of IC?

The conditon is 10 bit mode and pclk = 100MHz.

Best regards,

Hello,

Back channel frequency is 3.3MHz min. to 4.2MHz max. It can be found in the 914A datasheet.

I assume "sources in side of IC" is the internal PCLK frequency. It's 50MHz.

Dear Sugiura-san,

Thank you for your reply.

Aren't there any sourve of 30MHz signal in this iC, are there?
Is there only 50MHz for PCLK in this IC?

The noise problem occurred around 30MHz in the customer board.

Best regards,

Yamauchi-san,

There is no 30MHz signal in this device. When PDB is low, does the 30MHz noise go away?

Best Regards,
Sugiura
