XRT83SL38
OCTAL T1/E1/J1 SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER
JUNE 2007
REV. 1.0.2
GENERAL DESCRIPTION
The XRT83SL38 is a fully integrated Octal (eight
channel)
short-haul
line
interface
unit
for
T1
(1.544Mbps) 100
Ω, E1 (2.048Mbps) 75Ω or 120Ω, or
J1 110
Ω applications.
In T1 applications, the XRT83SL38 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
arbitrary pulse generators are available in both T1
and E1 modes).
The XRT83SL38 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
XRT83SL38 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
Ω,
100
Ω, 110Ω and 120Ω 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.
