Please tell me how LMH1982 detects H_ERROR.
When (Hsync input / reference divider) and (VCXO clock / feedback divider) has phase error, there should be some "threshold" or "Time Window" for LMH1982 to decide the reference is not present. (How the device decide H_ERROR).
.
What is the "Threshold" or "Time Window" for the device to detect H_ERROR ?
Please also tell us, whether the Time Window is generated based on (VCXO clock / feedback divider) or (Hsync input / reference divider) .
.
I have read the datasheet P.21, "6.1 Reference Detection" and "6.1.1 Programming the Loss of Reference Threshold".
