CDCV304: Input clock slew rate spec

Part Number: CDCV304
Other Parts Discussed in Thread: LMK1C1104,

Hi Experts,

Is there any spec related to input clock slew rate? Below is that one from LMK1C1104.

It seems that there is no this kind of spec for CDCV304.

Regards,

Uchikoshi

    Hi Uchikoshi, 

    Input slew rate specification was tested for LMK1C1104. That's why its in the datasheet. I was not able to find any test data for CDCV304 device specification. PCIx input slew spec is around 1-4 V/ns so you could reference that.  I did a quick measurement in the lab and 0.1 V/ns for CDCV304 should be good value for the minimum value as well. Could you tell why we don't want to use LMK1C1104 because it has better performance and its a P2P replacement.

    Best,
