LMK05028: Reference Input Monitoring Information

Part Number: LMK05028

Hello Guys,

Good day.

Our customer is working on LMK05028 clock synchronization chip. The data sheet explains that the following input monitors are included to evaluate the validity of the reference clock: Reference Validation Timer, Amplitude Monitor, Missing Pulse Monitor (Late Detect), Runt Pulse Monitor (Early Detect), Frequency Monitoring, and Phase Validation Monitor for 1-PPS Inputs.

The question is: when one of these monitors determines a reference clock is invalid, is there a way to detect which specific monitor caused the invalidation? E.G., If the Frequency Monitor invalidates the input because the reference input does not meet the frequency threshold, is there a way to determine that this was the exact reason?

Thanks in advance!
