CDCE62002 Clock: Use sinewave as REFCLK?

Hi,

I am planning to use the CDCE62002 Clock Generator. Now I am wondering if CDCE62002 can use a sinewave as refclk input.

Are there any documents about this topic?

 

Thanks.

Regards,

Yang

    Hi Yang,

    See if this helps you. CDCM7005 is similar device as CDCE62002

    Hello Yang,

    that should be absolutely no problem. Just make sure you meet the minimum input swing requirements as defined in the data sheet page 8-9.

    Sid,

    the CDCM7005 is an excellent performing clock jitter cleaner but it requires an external VCXO, which adds cost to the system. For systems that only need to generate a clean reference clock from a crystal or systems that need a jitter cleaner but can tolerate jitter in the order of 1ps rms the CDCE62002 and the CDCE62005 are excellent devices to minimize the overal system cost.
