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.
