Description
Physical receive or transmit signal (– differential)
Physical receive or transmit signal (+ differential)
Physical transmit or receive signal (– differential)
Physical transmit or receive signal (+ differential)
3.3V analog V
Set physical transmit output current.
Pull-down this pin with a 11.8K 1% resistor to ground.
1.8V analog core power input from VDDCO (pin 42).
Physical receive or transmit signal (– differential)
Physical receive or transmit signal (+ differential)
Analog ground.
Physical transmit or receive signal (– differential)
Physical transmit or receive signal (+ differential)
Connect to Analog ground.
25 or 50MHz crystal/oscillator clock connections.
Pins (X1, X2) connect to a crystal. If an oscillator is used, X1 connects to a
3.3V tolerant oscillator and X2 is a NC.
Note: Clock is +/- 50ppm for both crystal and oscillator.
Switch MII transmit enable
MLL/FLL: Switch MII transmit data bit 3
RLL: Strap option: RMII mode Clock selection
PU = Enable REFCLKO_3 output
PD = Disable REFCLKO_3 output
Switch MII transmit data bit 2
RLL: Strap option: X1 pin Clock selection (for Rev A3 and behind A3)
PU = 25MHz to X1 pin as clock source (default).
PD = 50MHz to X1 pin as clock source to provide/receive 50MHz RMII
reference clock for RLL part.
Switch MII/RMII transmit data bit 1
Switch MII/RMII transmit data bit 0
Digital ground
3.3V, 2.5V or 1.8V digital VDD input power supply for IO with well
decoupling capacitors.
MLL/FLL: Switch MII transmit clock (MII and SNI modes only)
Output in PHY MII mode and SNI mode
Input in MAC MII and RMII mode.
RLL: Reference clock input
Note: pull up or down is needed if internal reference clock is used in RLL.
Switch port3 MII transmit error in MII mode
0= MII link indicator from host in MII PHY mode.
1= No link on port 3 MII PHY mode and enable By-pass mode.
