Ball Function

Port 1 physical receive (MDI) or transmit (MDIX) signal (+ differential)

Port 1 physical receive (MDI) or transmit (MDIX) signal (– differential)

Port 1 physical transmit (MDI) or receive (MDIX) signal (+ differential)

Port 1 physical transmit (MDI) or receive (MDIX) signal (– differential)

Test input 2

For normal operation, left this ball open.

Set physical transmits output current.

Pull-down this ball with a 3.01K 1% resistor to ground.

25MHz crystal or oscillator clock connection.

Balls (X1, X2) connect to a crystal. If an oscillator is used, X1 connects to a 3.3V

tolerant oscillator and X2 is a no connect.

Note: Clock requirement is ± 50ppm for either crystal or oscillator.

Hardware reset ball (active Low). This reset input is required minimum of 10ms

low after stable supply voltage 3.3V.
