LMX2594: SYSREF

Part Number: LMX2594
Other Parts Discussed in Thread: LMX2820

Tool/software:

Hi.

When I was adjusting the LMX2594 SYSREF delay, it seemed that as the f_interpolator frequency increased, the delay step size was overall decreasing. However, the datasheet states that the step size is fixed at 9 ps. Am I testing incorrectly, or is the step size frequency-dependent, similar to the LMX2820?"
