GENERAL DESCRIPTION
The XR-T5793 is an optimized line interface unit, built
using low power CMOS technology. This device contains
four independent E1 channels for primary rate, PCM
applications up to 2.048Mbps. Each channel performs
the driver and receiver functions necessary to convert
bipolar signals to TTL/CMOS compatible logic levels and
vice versa. The device supports single ended or balanced
line interfaces on each channel, thereby providing the
user an option of reducing system cost and board space
by replacing the transformer with a capacitor.
Each of the four drivers can be independently disabled,
allowing
maximum
flexibility
in
system
power
management.
Output pulses are fully CCITT G.703
compliant. Moreover, the return loss is at least 18dB over
a frequency range of 51kHz to 3.072MHz.
The slicing circuit in the receive path is able to tolerate a
maximum of 12dB of cable loss with a minimum input
sensitivity of 600mV over the operating temperature
range. Return loss on the receive interfaces is minimum
20dB from 51kHz to 3.072MHz.
Local and remote loopbacks can be performed on any of
the four channels.
A separate loss of signal (LOS)
detection circuitry and a LOS pin is provided for each
input.
The XR-T5793 is targeted for multi-line E1 line card
applications
where
real
estate
and
low
power
consumption are critical. Also, the device may be used in
T1 applications (1.544Mbps) which do not require
meeting the DSX-1 cross connect pulse template. The
XR-T5793 is pin compatible with the XR-T5794, which
supports a fifth channel.
The fifth channel is for
redundancy and dedicated monitoring on any of the eight
bipolar paths.
