DP83822HF: Ethernet PHY which can bypass 4B5B

Ryo Akashi

Part Number: DP83822HF

Hello experts,

I'm looking for Ethernet PHY which can support 100BASE-FX. DP83822HF is one candidate.

Also, I prefer the device which can bypass 4B5B translator, 25Mbps TXD[4..0]inout/RXD[4..0]output can transmit and receive to 125Mbps FXT/FXR directly. (which is called symbol mode?)

Do you have such kind of device?

Thanks and best regards,

Ryo Akashi

Hi Akashi-san,

I'm not sure I understand your question. The 100Base-FX needs to have 4B5B encoding to make the transmit rate of 125Mbps.

If 4B5B is bypassed, the line rate will not be 125Mbps.
