Hi team,

Is CDCDB800 possible to support XTAL input? The input frequency is 25MHz.

Hi Shunsuke,

CDCDB800 is a clock buffer and does not support crystal device as clock input.

For 25 MHz clock generation i would recommend clock generator CDCE813-Q1
If CDCE813-Q1 is the best choice depends on the application requirments.

Regards,
Octo

Hi Oct-san,

Thank you for the answer and the device proposal. The output format is LP-HCSL, so CDCE813-Q1 isn't applicable for thjs opportunity.

I'm sorry that I didn't mention the customer's requirements, so I'll let you know later.

Best regards,

Shunsuke Yamamoto
