Pin Function
1.8V analog power supply from VDDCO (pin 24) with appropriate filtering. If VDDIO is
1.8V, this pin must be supplied power from the same source as pins 10, 79, 92, 108 and
125 (VDDIO) with appropriate filtering.
Analog ground

Set physical transmits output current.
Pull-down this pin with a 3.01K 1% resistor to ground.
Analog ground
1.8V analog power supply for PLL from VDDCO (pin 24) with appropriate filtering. If
VDDIO is 1.8V, this pin must be supplied power from the same source as pins 10, 79, 92,
108 and 125 (VDDIO) with appropriate filtering.
Analog ground
25MHz crystal or oscillator clock connection.
Pins (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.
Reset Not
Hardware reset pin (active Low). This reset input is required minimum of 10 ms low after
stable supply voltage 3.3V.
No Connect.
