GENERAL DESCRIPTION
The XRT59L91 is an optimized single-chip analog 3.3V
E1 line interface unit (LIU) fabricated using low power
CMOS technology. The LIU IC consists of both a
Transmitter and a Receiver function. The Transmitter
accepts a TTL or CMOS level signal from the Terminal
Equipment; and outputs this data to the line via bipolar
pulses that are compliant to the ITU-T G.703 pulse
template for E1. The Receiver accepts an attenuated
bipolar line signal (from the remote terminal equipment)
and outputs this data to the (near-end) terminal equip-
ment via CMOS level signals.
The receiver input can be transformer or capacitively-
coupled to the line. The receiver input is transformer-
coupled to the line, using the 2:1 step-down trans-
former. The transmitter is coupled to the line using a
1:2 step-up transformer. This same configuration is
applicable for both balanced (120W ) and unbalanced
(75W ) interfaces.
