XRT83SL30
SINGLE-CHANNEL T1/E1/J1 SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
MAY 2003
REV. P1.0.4
GENERAL DESCRIPTION
The XRT83SL30 is a fully integrated single-channel
short-haul line interface unit for T1(1.544Mbps) 100
,
E1(2.048Mbps) 75
or 120
and J1 110
applica-
tions.
In T1 applications, the XRT83SL30 can generate five
transmit pulse shapes to meet the short-haul Digital
Cross-Connect (DSX-1) template requirements.
The XRT83SL30 provides both Serial Host micropro-
cessor interface and Hardware Mode for program-
ming and control. Both B8ZS and HDB3 encoding
and decoding functions are included and can be dis-
abled as required. On-chip crystal-less jitter attenua-
tor 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 XRT83SL30 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. For the receiver this is accomplished
with internal resistors or through the combination of
one single fixed value external resistor and program-
mable internal resistors. In the absence of the power
supply, the transmit output and receive input 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 va-
riety of external clock sources.
