F0
Mode control input.
11
7
E0
Detector Output Selection Input. This TTL input controls the multiplexing of the SHD (E0 = 1) and GKD (E0 = 0)
comparator outputs to the DET output based upon the state at the F2-F0 pins (see the Device Operating Modes table
shown on page 2).
12
9
DET
Detector Output - This TTL output provides on-hook/off-hook status of the loop based upon the selected operating
mode. The detected output will either be switch hook, ground key or ring trip (see the Device Operating Modes table
shown on page 2). DET will be latched low following a ring trip. Unlatching the DET pin is accomplished by changing
logic state.

10
ALM
Thermal Shutdown Alarm. This pin signals the internal die temperature has exceeded safe operating temperature
(approximately 175°C) and the device has been powered down automatically.
14
11
AGND
Analog ground reference. This pin should be externally connected to BGND.
15
12
BSEL
Selects between high and low battery, with a logic “1” selecting the high battery and logic “0” the low battery.
16
13
TL
Programming pin for the transient current limit feature, set by an external resistor to ground.
17
14
POL
External capacitor on this pin sets the polarity reversal time.
18
15
VRS
Ringing Signal Input - Analog input for driving 2-wire interface while in Ring Mode.
19
17
AUX
Auxiliary input - Float if not used.
20
18
VTX
Transmit Output Voltage - Output of impedance matching amplifier, AC couples through a resistor to CODEC.
21
19
VFB
Feedback voltage for impedance matching. This voltage is scaled to accomplish impedance matching. The CFB
capacitor connects between this pin and the -IN pin. The CFB cap needs to be non-polarized for proper device
operation in the Reverse Active mode. Ceramic surface mount capacitors (1206 body style) are available from
Panasonic with a 6.3V voltage rating. These can be used for CFB since it is internally limited to approximately ±3V.
22
20
-IN
Analog Receive Voltage - 4-wire analog audio input voltage. connects to CODEC via receive gain setting resistor R
IN
(see Figure 18). Resistor R
IN
needs to be as close to the -IN pin as possible to minimize parasitic capacitance.
23
21
VCC
Positive voltage power supply,+3.3V
24
22
CDC
DC Biasing Filter Capacitor - Connects between this pin and V
CC
.The CDC capacitor may be either polarized or non
polarized with a 6.3V voltage rating.
25
23
RT
Ring trip filter network.
26
24
ILIM
Loop Current Limit programming resistor.
27
25
SH
Switch hook detection threshold programming resistor.
---
26
SCC
Substrate Common Connection - Connect this pin to VBH Supply. This pin is used to connect the substrate of the die
and the thermal heatsink plane of the QFN package.
28
27
RING
RING power amplifier output.
