CDCM7005: Need for REFCLK

Ryuuichi machida

Part Number: CDCM7005
Other Parts Discussed in Thread: CDCLVP111, ,

Hi

I understand that CDCLVP111 is best solution for the following usage.
But, I would like you to confirm about following question.

Q. When user do not use PRI_REF and SEC_REF and use only VCXO_IN from another IC, can this device work correctly ?
(According to block diagram, VCXO_IN go back to input circuit. So when user can not use this device without PRI_REF or SEC_REF, please let me know.)

Hi Ryuuichi,

This functionality is called distribution mode or buffer mode.

Below is the thread for space version of CDCM7005 and it should be valid for industrial part also.

Hello Pal-san,

Thank you for your reply.
Since I wrote just CDCM7005, but my case is also space grade(in fact parts num is CDCM7005-SP)
This is what I want to confirm. Thank you.
