CY27410 connection

[hata_3396041]

Hello 

It would be very helpful if you could answer quickly.

1. I would like to use CY27410 as the CLKBuffer of PCIe. Is there a reference circuit?

2. Regarding the following data sheet, is it necessary to input the same PCIe CLK to the input terminals (IN1, 2) even when using it as a buffer?

Or is it only when using ZDB?

Best Regards

Haya

Hi @hata_3396041 ,

1) We can provide you our app note for PCIe solutions which will be helpful for your reference.

2) The feedback to the input is specific to the ZDB mode and not applicable for the buffer mode.

Thanks,

Pradipta.
