Functionality
TIP
1
29
Tip power amplifier output.
BGND
2
30
Battery Ground - To be connected to zero potential. All loop current and longitudinal
current flow from this ground. Internally separate from AGND, it is recommended that
it is connected to the same potential as AGND.
VBL
3
31
Low Battery supply connection.
VBH
4
32
High Battery supply connection for the most negative battery.
SW+
5
1
Uncommitted Switch positive terminal.
SW-
6
2
Uncommitted Switch negative terminal.
SWC
7
3
Switch Control Input. This TTL compatible input controls the uncommitted switch, with
a logic “0” enabling the switch and logic “1” disabling the switch.
F2
8
4
Mode Control Input - MSB.
Pins F2-F0 TTL inputs control the various modes of operation of the device.
F1
9
5
Mode Control Input. (see F2 above)
F0
10
6
Mode Control Input. (see F2 above)
E0
11
7
Detector Output Selection Input. TTL input controling the multiplexing of the Switch
Hook Detector (E0=1) and Ground Key Detector (E0=0) comparator outputs to the
DET output based upon the state at the F2-F0 pins (see the Device Operating
Modes table in section 7).
DET
12
9
Detector Output - This TTL output provides on-hook/off-hook status of the loop based
upon the selected operating mode (F2-F0 pins). The detected output will either be
switch hook, ground key or Ring Trip.
ALM
13
10
Thermal Shutdown Alarm. Signals internal die temperature has exceeded safe
operating temperature (approximately 175oC) and the device has been powered down
automatically.
AGND
14
11
Analog Ground Reference. This pin should be externally connected to BGND.
BSEL
15
12
Selects between high battery (BSEL=”1”) and low battery (BSEL=”0”).
TL
16
13
Transient Current Limit programming resistor
POL
17
14
Polarity Reversal Time programming capacitor
VRS
18
15
Ringing Signal Input - Analog input for driving 2-wire interface while in Ring Mode.
VRX
19
17
Analog Receive Voltage - Analog audio input voltage. AC couples to CODEC.
VTX
20
18
Transmit Output Voltage - Output of impedance matching amplifier, AC couples to
CODEC.
VFB
21
19
Feedback voltage for impedance matching. This voltage is scaled to accomplish
impedance matching.
-IN
22
20
Impedance matching amplifier summing node.
VCC
23
21
Positive voltage power supply, usually +5V.
CDC
24
22
DC Biasing Filter Capacitor connects between this pin and VCC.
RTD
25
23
Ring Trip filter network.
ILIM
26
24
Loop Current Limit programming resistor.
RD
27
25
Switch hook detection threshold programming resistor.
RING
28
27
Ring power amplifier output.
