Pin Descriptions
PLCC SYMBOL
DESCRIPTION
1
TIP TIP Power Amplifier Output.
2
BGND Battery Ground - To be connected to zero potential. All loop current and longitudinal current flow from this ground.
Internally separate from AGND and SGND but should be connected to the same potential as AGND & SGND.
3
V_BL
Low Battery Supply Connection.
4
V_BH High Battery Supply Connection.
5
BSEL Selects between high and low battery, with a logic “1” selecting the high battery and logic “0” the low battery.
6
F2
TTL Mode Control Input - MSB.
7
F1
TTL Mode Control Input.
8
F0
TTL Mode Control Input - LSB.
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 or ring trip.
10
V_RSP Non-Inverting Ringing Signal Input - Analog input for driving 2-wire interface while in Ring Mode.
11
V_RSM Inverting Ringing Signal Input - Analog input for driving 2-wire interface while in Ring Mode.
12
V_TXP Transmit Output Voltage - AC couples to CODEC.
13
V_TXM Transmit Output Voltage - AC couples to CODEC.
14
AGND Analog Ground Reference. This pin should be externally connected to BGND.
15
POL An External Capacitor on this pin sets the polarity reversal time.
16
V_RXP Non-Inverting Analog Receive Voltage - 4-wire analog audio input voltage.
17
V_RXM Inverting Analog Receive Voltage - 4-wire analog audio input voltage.
18
V_ZO Connection Terminal for impedance matching programming resistor
19
-IN
Connection Terminal for high pass filter capacitor and impedance matching components.
20
V_FB Connection Terminal for high pass filter capacitor and impedance matching components.
21
TL
Transient Current Limit Programming Resistor Connection Terminal.
22
V_CC Positive Voltage Power Supply, +5V +/-5%.
23
C_DCP DC Biasing Filter Capacitor - Positive Terminal.
24
C_DCM DC Biasing Filter Capacitor - Negative Terminal.
25
RTD Ring Trip Filter Network Connection Terminal.
26
I_LIM
Loop Current Limit programming resistor connection terminal.
27
RD
Switch Hook Detection threshold programming resistor connection terminal.
28
RING RING Power Amplifier Output.
