Description
I
Connects LC network with VCO1 pin to provide the tank circuit
for the received voltage control oscillator
¾ Normally connected to ground through a capacitor.
Receiver phase detector output. The PDT of RX-PLL detects
O phase errors from the received PLL. The output is connected to
external low pass filter.
Transmitter phase detector output. The PDT of TX-PLL detects
O phase errors from the transmitted PLL. The output is connected
to an external low pass filter.
¾ Digital ground
I
14-bit programmable transmit counter input. The output signal
from the external VCO circuit can be AC coupled to this pin.
