Hello All,
I am working on SFP receiver using ONET4251. I just wonder whether it is safe to leave the RSSI pin open (leave Pin 13 not connected). Is there any recomendation to terminate RSSI, consider the SFP interface utilise LOS instead RSSI and my current product do not have analysis circuit that utilise RSSI.
Thanks & Regards,
Reema Chahande
Reema,
It is safe to leave the RSSI pin open. It is an analog output so there is not a concern about a floating value that could get pulled in one direction.
Best regards,
