DESCRIPTION
Analog Positive Supply.
5.0 volts.
Reset Alarm Indication Signal.
Every other low pulse at this input
establishes the AIS alarm detection period.
0 Code Suppression Enable.
When high, incoming B8ZS (RCLKSEL=0)
or HDB3 (RCLKSEL=1) code words are replaced with all 0s at RPOS and
RNEG; when low, no code replacement occurs.
Loop Cap.
Part of internal loop filter; attach a 10 microfarad capacitor from
this pin to V
SS
.
Receive Clock Select.
Tie to V
SS
for 1.544 MHz (T1) applications, to V
DD
for
2.048 MHz (CEPT) applications.
Receive Tip and Ring.
Connect to line transformer as shown in Figure 2.

Frequency Lock.
High state indicates that internal circuitry is phase- and
frequency-locked to the incoming signal at RRING and RTIP.
Analog Signal Ground.
0.0 volts.
Digital Signal Ground.
0.0 volts.
Receive Clock.
Extracted line rate clock.
Receive Data.
Extracted receive data; updated on rising edge of RCLK.

No Connect.
Do not connect to this pin.
Bipolar Violation.
Transitions high for the full bit period when a bit in
violation appears at RPOS or RNEG; B8ZS code words are not accused when
ZCSEN=1. BPV not valid for RCLKSEL=1 and ZCSEN=1.
Alarm Indication Signal.
High when the received data stream has contained

less than three 0s during the last two periods of the RAIS signal.
Receive Carrier Loss.
High if 192 0s appear at RPOS and RNEG; reset on
next occurrence of a one.
