Dear Sir/Madam,

 

Our customer is studying with your AD9552, AD9553 clock generator for their next development product.

 

Case-1 Output freq

267.3MHz , input(reference) freq=74.25MHz

Case-2 Output freq

267.032967MHz, input(refeerence freq=74.17582418MHz

Using Integer type

 

Question-1

How should we compare the jitter performance of similar model AD9552 and AD9553?

He confirmed the difference on your 2 datasheets, but didn’t catch the difference due to that the test condition different.

 

Question-2

What is the tolerance of input REF clock jitter AD9552?

The REF clock will be made by FPGA or PLL on external.

So he would like to know the tolerance.

 

Thanks Kaos
