Preliminary Information
MH89625C
17
CA
Control Address (Input):
A three-level digital input which enables PCM input and
output, and determines into which control register (A or B) the serial data, presented to
CSTi, is stored.
18
RGND
Relay Ground:
Return path for relay supply voltage.
19
RD2
Relay Driver 2:
Connects to a user provided external relay coil. A logic high at the SD1
output of the internal MT8967 codec activates this driver. An internal clamp diode from
VRLY to RD2 is provided. This relay is typically used for DID reversals.
20
RD1
Relay Driver 1.
Connects to a user provided external relay coil. A logic high at the SD0
output of the internal MT8967 codec activates this driver. An internal clamp diode from
VRLY to RD1 is provided. This relay is typically used for ringing.
21
RD3
Relay Driver 3.
Connects to a user provided external relay coil. A logic high at the SD2
output of the internal MT8967 codec activates this driver. An internal clamp diode from
VRLY to RD3 is provided. This relay is typically used for in-test.
22
RD4
Relay Driver 4:
Connects to a user provided external relay coil. A logic high at the SD3
output of the internal MT8967 codec activates this driver. An internal clamp diode from
VRLY to RD4 is provided. This relay is typically used for out-test.
23
V
RLY
Relay Positive Supply Voltage:
Normally +5V. Connects to the relay coil and the relay
supply voltage.
24
V
Ref
IC
Voltage Reference (Input):
+2.50V for the internal codec.

AGND
Analog Ground
. Analog and Digital Ground. Connects to System Ground.
31
V
DD
LCA
Positive Supply Voltage
(+5V)
32
Loop Current Adjust (Input).
The maximum constant loop current is a function of the
resistance connected from this pin to V
EE
. Normally left open
Internal Connection.
This pin is internally connected.
33
IC
34
VAC
Battery AC Component (Input).
AC noise present in the V
BAT
supply, isolated from the
DC component, can be applied to this pin to reduce longitudinal noise on TIP and RING.
To implement this feature, connect a 0.1
μ
F 100V capacitor from V
BAT
to VAC, and a 1k
resistor from VAC to AGND. This pin must be tied to AGND when not used.
35
GS
Gain Setting (Input
). A logic low at this input adds an additional -0.5dB gain in the
receive direction (DSTi to Tip-Ring). This gain is in addition to the gain set by the Codec.
A logic high adds 0dB gain.
36
LGND
Loop Ground.
Return path for the battery (V
BAT
) supply voltage. Connects to System
Ground.
37
V
Bat
IC
Battery Supply Voltage.
Normally -48V.
