CDCUN1208LP: Minimum Frequency (1PPS Support?)

ghweng1

Part Number: CDCUN1208LP

We would like to use the CDCUN1208LP to support both clock distribution and 1PPS timing reference distribution. The datasheet lists 0.008MHz, is this the 'TRUE' minimum operating frequency of this device or will it support lower frequencies such as a 1PPS?

Hello,

I don't believe CDCUN1208LP supports 1PPS but I can double check with our design team. However, I know that our LMK1D, LMK1C, and CDCLVC family of buffers definitely do support 1PPS. Would one of these fit your use case?

Connor

Connor,

Thank you, i would greatly appreciate if you don't mind checking. I am very familiar with those families and have them in the back pocket just in case. The CDCUN1208 is very flexible and has an evaluation board with onboard regulators that will make it very evaluation board for this device has onboard regulators that would have streamlined the process to test different scenarios. I look forward to the answer. I am looking for a device that can be used to distribute both 10MHZ and PPS with varying input strengths and flexible output strengths.

Sorry for the delayed response, I confirmed with the design team that the CDCUN1208LP does support 1PPS. Let me know if you have any other questions.
