XRT83VL38
OCTAL T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
AUGUST 2010
REV. 1.0.1
GENERAL DESCRIPTION
The XRT83VL38 is a fully integrated Octal (eight
channel) long-haul and short-haul line interface unit
for T1 (1.544Mbps) 100
, E1 (2.048Mbps) 75 or
120
J1 110or BITS Timing applications.
In long-haul applications the XRT83VL38 accepts
signals that have been attenuated from 0 to 36dB at
772kHz in T1 mode (equivalent of 0 to 6000 feet of
cable loss) or 0 to 43dB at 1024kHz in E1 mode.
In T1 applications, the XRT83VL38 can generate five
transmit pulse shapes to meet the short-haul Digital
Cross-Connect (DSX-1) template requirements as
well as for Channel Service Units (CSU) Line Build
Out (LBO) filters of 0dB, -7.5dB -15dB and -22.5dB
as
required
by
FCC
rules.
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 XRT83VL38 provides both a parallel/serial 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. Two on-chip
crystal-less jitter attenuators with a 32 or 64 bit FIFO
can be placed in the receive and the transmit paths
with
loop
bandwidths
of
less
than
3Hz.
The
XRT83VL38 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.
