Other Parts Discussed in Thread: DS110DF111

Hi Team,

Please tell me about the LOS indication (Pin13) of DS110DF111.

The pin description says, "Output is driven LOW when a valid signal is present on CH A. Output is released when signal on CH A is lost (LOS). "

Is LOS pin only monitoring channel A ??

Or, is it monitoring both Channel A and B, which would output Hi (with pull up) if either of the signal is lost ??

Best Regards,

Does DS110DF111 LOS pin (Pin13) indicates only Channel A or does it also monitor Channel B ?

Pin 13 Output is driven LOW when a valid signal is present on CH A. Output is

released when signal on CH A is lost (LOS).

Mark-san,

Thank you very much.

So, Pin13 Output will ignore LOS status of Channel B, correct ?

That is correct - Pin 13 only reports on the status for Channel A.
