PHY remote testing
« on: April 18, 2024, 06:08:23 am »
When setting KSZ9131RNX to Remote Loopback, in addition to the register settings, there is a description that says "Connect RX_CLK to TX_CLK".



Q1.Does this mean physically connecting Pin to Pin?



Q2.If the above is correct, there are no pins named RX_CLK and TX_CLK, but does RX_CLK mean RXC (35 pin) and TX_CLK mean TXC (24 pin)?

Search "_CLK" and some say yes and some say no.

It's like mixed software and hardware thing.

Q1.It means physically connecting the RX_CLK pin to the TX_CLK pin.

Q2. RX_CLK and TX_CLK are not directly labelled as such on the datasheet pinout. However, RX_CLK typically refers to the Receive Clock and TX_CLK refers to the Transmit Clock.
