Dear Experts,

My customer wants to ask you about the following question in HMC7043. Could you please reply to the following question?

Q1: Can HMC7043 work with the following clock frequency values correctly?

1) CLKIN frequency range: 200[MHz] to 3200[MHz].
2) RFSYNCIN frequency value: 1.44[MHz] (:= 1440[kHz]).

Especially, my customer is concerned whether or not HMC7043 can accept the RFSYNCIN frequency value at 1440[kHz]?

Could you please advise my customer about your reply to the above question?

I believe that the RFSYNCIN frequency value is not so much critical for HMC7043. It should be a system issue of the customer, not HMC7043. It will be upto whether or not how much precisely SYSREF signal edges generated by a HMC7043 must be synchronized with other SYSREF signal edges generated by other clock devices except the HMC7043.

Thanks and regards.
