3/6-Port DS3/E3/STS-1 Integrated
Line Termination Device for Transport
M29323/6 –“Line-Card-on-a-Chip”
The M29323/6 provides a complete physical-layer solution
>
KEY FEATURES
for flexible DS3/E3/STS-1 clear channel services. The
M29323/6 aggressively drives down cost for existing solu-
tions and as well as reduces PCB real-estate and power.
> High integration – LIUs with
DJAT, DS3/E3
framers/mappers, STS-1
framers/mappers, STS-
12/STM-4 framer
> Parallel 8-bit, 77.76 MHz TDM
telecom bus
> Embedded CLADs for
supported line rates
Each port of the M29323/6 operates independently allowing
for a mix of DS3, E3 or STS-1 on the same device. This
enables ADMs/OEDs and MSPPs to deploy a single line card
that supports the simultaneous mapping for SDH or SONET
transport of both DS3 and E3.

for BERT
> Flexibility – mix DS3, E3 and
STS-1 on one device
> Comprehensive loopbacks
> Easy implementation –TAP
software + high integration
= faster time-to-market
The M29323/6 includes 3/6 independent DS3/E3/STS-1 line
interface units (LIUs) with built-in digital jitter attenuators
(DJAT), 6/12 DS3/E3 framers and 3/6 STS-1 framers. Each
port is capable of supporting DS3/E3/STS-1
In addition, the M29323/6 supports pseudo-random bit
sequence (PRBS) testing and a full set of loopback
functions at different functional blocks.
mapped/demapped signals to/from SONET/SDH.
The M29323/6 line side interfaces support electrical
DS3/E3/STS-1, requiring only the addition of transformers
and passive termination. The M29323/6 system interface
supports STS-12/STM-4 for the SONET/SDH traffic via a
standard 8-bit, 77 MHz TDM telecom bus. Thus, a channelized
OC-12/STM-4 or OC-3/STM-1 can be broken down to
DS3/E3/STS-1 streams by the M29323/6 on a channel-by-
channel basis.
Using the telecom application package (TAP) software
to abstract the physical registers, developers can easily
implement the M29323/6 solution, reducing design time.
The M29323/6 are offered in a 27mm FCBGA package.
The M29323/6 requires only one 19.44 MHz reference clock
(passive crystal) or 77.76/155.52 MHz SONET reference
clock for generating all the necessary internal line rate
clocks. The generated clocks are also available through
an output pin.
