Polarity Reversal Slowdown Capacitor.
Connect a capacitor from
this node to ground for controlling rate of battery reversal. If ramped
battery reversal is not desired, this pin is left open.

Protected Tip.
The output drive of the tip amplifier and input to the
loop sensing circuit. Connect to loop through overvoltage and overcur-
rent protection.
Protected Ring.
The output drive of the ring amplifier and input to the
loop sensing circuit. Connect to loop through overvoltage and overcur-
rent protection.
State Control Input.
These pins have an internal 110 k
pull-down.

Transmit Gain.
Input to AX amplifier. Connect a 4.75 k
resistor from
this node to VTX to set transmit gain. Gain shaping for termination
impedance with a first-generation codec is also achieved with a net-
work from this node to VTX.
ac Output Voltage.
Output of internal AX amplifier. The voltage at this
pin is directly proportional to the differential tip/ring current.
ac/dc Separation.
Input to internal AAC amplifier. Connect a 0.1
μ
F
capacitor from this pin to VTX.

0 = off-hook or ring trip or TSD.
1 = on-hook and no ring trip and no TSD or DISCONNECT state.
0 = no ring or tip ground.
1 = ring or tip ground.
