Analog Ground.
All ground pins should be connected to the ground plane of the circuit board.
+5 V Analog Power Supply.
This pin should be bypassed to ground using 0.1 F capacitor. All power supply pins should be connected to
the power plane of the circuit board.
Voice Frequency Receiver Output.
This is the output of receive power amplifier. It can drive 2000
Gain Setting Transmit Amplifier Output.
This pin is the output of the gain setting amplifier, and the input to the differential transmit filter. It should be
connected to the corresponding VFXI pin through a resistive network to set the transmit gain. Refer to Figure
5 for details.
Voice Frequency Transmitter Input.
This pin is the input to the gain setting amplifier in the transmit path.
SLIC Signaling Output for Channel 3.
SLIC Signaling Output for Channel 2.
