XRT83L34
QUAD T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
FEBRUARY 2005
REV. 1.0.1
GENERAL DESCRIPTION
The XRT83L34 is a fully integrated Quad (four
channel) long-haul and short-haul line interface unit
for T1 (1.544Mbps) 100
Ω, E1 (2.048Mbps) 75Ω or
120
Ω, or J1 110Ω applications.
In long-haul applications the XRT83L34 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 XRT83L34 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
XRT83L34
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
XRT83L34 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.
