Am79M576A Data Sheet
PIN DESCRIPTIONS
Pin Names
Type
Description
AGND
Gnd
Analog (quiet) ground
A(TIP)
Output
Output of A(TIP) power amplifier
BGND
Gnd
Battery (power) ground
B(RING)
Output
Output of B(RING) power amplifier
C3
–
C1
Input
Decoder. TTL compatible. C3 is MSB and C1 is LSB.
CHCLK
Input
Chopper clock. Input to switching regulator (TTL compatible). Freq = 256 kHz (Nominal).
CHS
Input
Chopper Stabilization. Connection for external stabilization components.
DA
Input
Ring-trip negative. Negative input to ring-trip comparator.
DB
Input
Ring-trip positive. Positive input to ring-trip comparator.
DET
Output
Detector. When enabled, a logic Low indicates that the selected detector is tripped. Logic inputs
C3
–
C1, E1, and E0 select the detector. Open-collector with a built-in 15 k
pull-up resistor.
DGND
Gnd
Digital ground
E0
Input
A logic High enables DET. A logic Low disables DET.
E1
Input
Ground-key enable. E1 = High connects the ground-key detector to DET, and E1 = Low connects
the off-hook or ring-trip detector to DET.
HPA
Capacitor
High-pass filter capacitor. A(TIP) side of high-pass filter capacitor.
HPB
Capacitor
High-pass filter capacitor. B(RING) side of high-pass filter capacitor.
L
Output
Switching Regulator Power Transistor. Connection point for filter inductor and anode of catch
diode. Has up to 60 V of pulse waveform and must be isolated from sensitive circuits. Keep the
diode connections short because of the high currents and high di/dt.
QBAT
Battery
Quiet Battery. Filtered battery supply for the signal processing circuits.
RD
Resistor
Detector resistor. Threshold modification and filter point for the off-hook detector.
RDC
Resistor
DC feed resistor. Connection point for the DC feed current programming network, which also
connects to the Receiver Summing Node (RSN). V
RDC
is negative for normal polarity and positive
for reverse polarity.
RINGOUT/
DGND
Output
Relay ground for 5 V relays
—
externally connected to DGND.
RSN
Input
The metallic current (AC and DC) between A(TIP) and B(RING) is equal to 1000 x the current into
this pin. The networks that program receive gain, two-wire impedance, and feed current all
connect to this node.
TP
Thermal
Thermal pin. Connection for heat dissipation. Internally connected to substrate (QBAT). Leave as
open circuit or connected to QBAT. In both cases, the TP pins can connect to an area of copper
on the board to enhance heat dissipation.
VBAT
Battery
Battery supply
VCC
Power
+5 V power supply
VCCRING
Input
Ring relay driver (sinks current to RINGOUT).
VEE
Power
–
5 V power supply
VREG
Input
Regulated Voltage. Provides negative power supply for power amplifiers, connection point for
inductor, filter capacitor, and chopper stabilization.
VTX
Output
Transmit Audio. This output is 0.510 times the A(TIP) and B(RING) metallic voltage.The other end
of the two-wire input impedance programming network connects here.
