Other Parts Discussed in Thread: DP83822HF, DP83822EVM
Hello Team,
We are tying to replace KSZ8041FTLI in our customer's project with DP83822IF.
First tests was succesfull, but the customer faced with one probelm.
They need to ensure data integrity in duplex mode, so if the connection was lost in one direction(link failed) - it is necessary to notify the remote phy in second direction.
Then remote phy should instantly(less than 2 ms) turn off the link signal.
Microchip has mode for this case, described in datasheet - Far-End Fault(When 2 KSZ8041FTLI linked):
A Far-End Fault (FEF) occurs when the signal detection is logically false on the receive side of the fiber transceiver. The KSZ8041FTL detects a FEF when its FXSD input (pin 48) is between 1V and 1.8V. When a FEF is detected, the KSZ8041FTL signals its fiber link partner that a FEF has occurred by transmitting a repetitive pattern of 84-ones and 1- zero. This pattern is used to inform the fiber link partner that there is a faulty link on its transmit side.
Does DP83822IF has similar mode? How to use it?
BR,
Ilya
