Set physical transmit output current.
Pull-down this pin with a 3.01K 1% resistor to ground.
Analog ground
1.2V analog V
Analog ground.
25MHz 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 no connect.
Note: Clock is +/- 50ppm for both crystal and oscillator.
Hardware reset pin (active low)
Unused pin – externally pull down for normal operation
