XRT83SL34
QUAD T1/E1/J1 SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
FEBRUARY 2004
REV. P1.0.8
GENERAL DESCRIPTION
The XRT83SL34 is a fully integrated Quad (four
channel)
short-haul
line
interface
unit
for
T1
(1.544Mbps) 100
, E1 (2.048Mbps) 75 or 120, or
J1 110
applications.
In T1 applications, the XRT83SL34 can generate five
transmit pulse shapes to meet the short-haul Digital
Cross-Connect (DSX-1) template requirements. It
also
provides
programmable
transmit
pulse
generators for each channel that can be used for
output
pulse
shaping
allowing
performance
improvement over a wide variety of conditions.
The XRT83SL34 provides both a parallel Host
microprocessor interface as well as a Hardware
mode for programming and control.
Both the B8ZS and HDB3 encoding and decoding
functions are selectable as well as AMI. An on-chip
crystal-less jitter attenuator with a 32 or 64 bit FIFO
can be placed either in the receive or the transmit path
with
loop
bandwidths
of
less
than
3Hz.
The
XRT83SL34 provides a variety of loop-back and
diagnostic features as well as transmit driver short
circuit detection and receive loss of signal monitoring.
It supports internal impedance matching for 75
,
100
, 110 and 120 for both transmitter and
receiver. In the absence of the power supply, the
transmit outputs and receive inputs are tri-stated
allowing
for
redundancy
applications
The
chip
includes an integrated programmable clock multiplier
that can synthesize T1 or E1 master clocks from a
variety of external clock sources.
APPLICATIONS
T1 Digital Cross-Connects (DSX-1)
ISDN Primary Rate Interface
CSU/DSU E1/T1/J1 Interface
T1/E1/J1 LAN/WAN Routers
Public switching Systems and PBX Interfaces
T1/E1/J1 Multiplexer and Channel Banks
