M1
Mode Select 1 Input.
The second of two mode select pins that is used to select the operation of the
serial port/DSP interface.

C1A
Isolation Capacitor 1A.
Connects to one side of the isolation capacitor C1. Used to communicated
with the line-side device.
12
8
GND
Ground.
Connects to the system digital ground.

V
A
Analog Supply Voltage.
Provides the analog supply voltage for the Si3021, nominally 5 V. This supply
is typically generated internally with an on-chip charge pump set through a
control register.

M0
Mode Select 0 Input.
The first of two mode select pins that is used to select the operation of the
serial port/DSP interface.
15
11
RGDT/FSD
Ring Detect/Delayed Frame Sync Output.
Output signal that indicates the status of a ring signal. Produces an active
low rectified version of the ring signal. When daisy chain is enabled, this sig-
nal becomes a delayed frame sync to drive a slave device.
16
12
OFHK
Off-Hook Input.
An active low input control signal that provides a termination across TIP and
RING for line seizing and pulse dialing.
