Pin Function, Note 2-2

Physical receive signal - (differential).

Analog ground.

Physical transmit signal + (differential).

Physical transmit signal - (differential).

3.3V analog VDD.

FQX: This pin can be floating when port 3 is used as copper port

(default). Port 3 can be set to fiber mode by Register 239 bit [7], this

pin is used for fiber signal detect pin on Port 3 in Fiber mode.

MQX/RQX/MLX: no connection.

FQX: Fiber signal detect pin for Port 4.

MQX/RQX/MLX: no connection.

No connection. Leave NC pin floating.

No connection. Leave NC pin floating.

No connection. Leave NC pin floating.

No connection. Leave NC pin floating.

Full-chip power down. Active low.

Interrupt. This pin is Open-Drain output pin.

Digital ground.

1.2V digital core VDD.

PHY [5] MII/RMII transmit enable.

MQX/FQX/MLX: PHY [5] MII transmit bit 3.

RQX: no connection for RMII.

MQX/FQX/MLX: PHY [5] MII transmit bit 2.

RQX: no connection for RMII.

PHY [5] MII/RMII transmit bit 1.

PHY [5] MII/RMII transmit bit 0.

MQX/FQX/MLX: PHY [5] MII transmit error.

RQX: no connection for RMII.

MQX/FQX/MLX: Output PHY [5] MII transmit clock

RQX: Input PHY [5] RMII reference clock, 50 MHz ±50 ppm, the

50 MHz clock comes from PMRXC Pin 60.

Digital ground.
