Hello everyone,
We are working with the DP83640 PHY using fiber mode and wanted to ask about the FX_SD signal. The fiber transceiver we are using has a 3.3V TTL Signal Detect output, would this be an issue given the FX_SD is PECL? Can it be connected directly? Do we need a level translator or will adding the PÊCL termination resistors enough?
Any help will be welcomed!
Regards.
