voltage protection requirements
GENERAL DESCRIPTION
The XRT59L91 is an optimized single-chip analog E1
line interface unit (LIU) fabricated using low power,
3.3V CMOS technology. The LIU IC consists of both
a Transmitter and a Receiver function. The Transmit-
ter 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 equipment via CMOS level signals.

l Test Equipment
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 (120
) and unbalanced
(75
) interfaces.
