Other Parts Discussed in Thread: LMH1297
Tool/software:
Good morning,
I am in production (5 years) with a board capable of SDI 12G.
Up to now no issue found on this I/F.
Please, look at the block diagram in attachment.
I have identified 2 point of test: point A and Point B.
Point A.
I do not see always the signal at this output (Out 0 of LMH1219)
Some times the signal is not present.
Some times the signal is present and stays present for ever.
Point B
the signal here is always present even when at point A is not.
The signal here is always stable.
Conclusion:
LMH1219 is able to receive and equalize the 12G at input and can transmit it to the LMH1297.
Lock signal moves correctly when I connect 12G input.
I do not explain the reason why Out 0 is not stable.
Do you have any idea- suggestion to investigate?
