CMOS HDB3 (High Density Bipolar 3)
Transcoder for 2.048/8.448Mb/s
Transmission Applications
The CD22103A is an LSI SOS integrated circuit which
performs the HDB3 transmission coding and reception
decoding functions with error detection. It is used in
2.048Mb/s and 8.448Mb/s transmission applications. The
CD22103A performs HDB3 coding and decoding for data
rates from 50Kb/s to 10Mb/s in a manner consistent with
CCITT G703 recommendations.
HDB3 transmission coding/reception decoding with code
error detection is performed in independent coder and
decoder sections. All transmitter and receiver inputs/outputs
are TTL compatible.
The HDB3 transmitter coder codes an NRZ binary unipolar
input signal (NRZ-IN) and a synchronous transmission clock
(CTX) into two HDB3 binary unipolar RZ output signals
(+HDB3 OUT, -HDB3 OUT). The TTL compatible output
signals +HDB3 OUT, -HDB3 OUT are externally mixed to
generate ternary bipolar HDB3 signals for driving
transmission lines.
The receiver decoder converts binary unipolar inputs
(+HDB3 IN, -HDB3 IN), which were externally split from
ternary bipolar HDB3 signals, and a synchronous clock
signal (CRX) into binary unipolar NRZ signals (NRZ-OUT).
The CD22103A operates with a 5V ±10% power supply
voltage over the full military temperature range at data rates
from 50Kb/s up to 10Mb/s.

Functional Description
The CD22103A is designed to code and decode HDB3
signals which are coded as binary digital signals (NRZ-lN)
and (+HDB3 IN, -HDB3 IN), accompanied by sampling
clocks (CTX) and (CRX). The two binary coded HDB3 out-
puts, (+HDB3 OUT, -HDB3 OUT) may be externally mixed to
create the ternary HDB3 signals (See Figure 1).
The two binary HDB3 input signals have been split from the
input ternary HDB3 in an external line receiver.
The receiver decoder converts binary unipolar inputs (+HDB3 IN,
-HDB3 IN), which were externally split from ternary bipolar HDB3
signals, and a synchronous clock signal (CRX) into binary unipolar
NRZ signals (NRZ-OUT).
Received signals not consistent with HDB3 coding rules are
detected as errors. The receiver error output (ERR) is active high
during one CRX period of each bit of received data that is inconsis-
tent with HDB3 coding rules.
An input string consisting of all ones (or marks) is detected and
signaled by a high level at the Alarm Signal (AIS) output. The AIS
output is set to a high level when less than three zeros are
received during two consecutive periods of the Reset Alarm Inhibit
Signal (RAIS). The AIS output is subsequently reset to a low level
when three or more zeros are received during two periods of the
reset signal (RAIS).
A diagnostic Loop-Test Mode may be entered by driving the Loop
Test Enable Input (LTE) high. In this mode the HDB3 transmitter
outputs (+HDB3 OUT, -HDB3 OUT) are internally connected to
70
the HDB3 receiver inputs, and the external HDB3 receiver inputs,
and the external HDB3 receiver inputs (+HDB3 IN, -HDB3 IN) are
disabled. The NRZ binary output signal (NRZ - OUT) corresponds
to the NRZ binary input signal (NRZ - IN) delayed by approxi-
mately 8 clock periods.
The Clock Receiver Output (CKR) is the product of the two HDB3
input signals or-ed together. The CRX clock signal may be derived
from the CKR signal with external clock extraction circuitry. In the
Loop Test Mode (LTE = 1) CKR is the product of the +HDB3 OUT
and -HDB3 OUT signals or-ed together.
The CD22103A may also be used to perform the AMI to NRZ
coding/decoding function. To use the CD22103A in this mode, the
HDB3/AMI control input is driven low.
Error Detection
Received HDB3/AMl binary input signals are checked for
coding violations, and an error signal (ERR) is generated as
described below.
• HDB3 Signals HDB3/AMl = High
The error signal (ERR) is flagged high for one CTX period if
a violation pulse (±V) is received of the same polarity as the
last received violation pulse.
A violation pulse (±V) is considered a reception error and
does not cause replacement of the last string of 4 bits to
zeros, if:
