LMX2592: S/E vs Differential Reference clock

Marjorie Catt

Part Number: LMX2592

Hi Dean,

With regard to performance, is it better to drive the input reference clock to the LMX2592 (OSCinP/M) single-ended or differentially?

Thanks,

Marjorie

Hi Marjorie,

I don't see a significant difference between SE and Diff input. What is important is the slew rate of the ref clock. A square wave clock is preferred.
