GENERAL DESCRIPTION
The XRT7295AE E3 Integrated Line Receiver is a fully
integrates receive interface that terminates a bipolar
E3 (34.3684 Mbps) signal transmitted over coaxial
Cable. This device can be used with the XRT7296
Integrated Line Transmitter (see Figure 10),
The device provides the functions of receive equaliza-
tion (optional) automatic gain control (AGC), clock
recovery and data re-timing, loss of signal and loss-of
frequency lock detection. The digital system interface
is a dual-rail with received positive and negative 1s
appearing as unipolar digital signals on separate output
leads. The on-chip equalizer is designed for cable
losses of 0 to 15dB. The receive input has a variable
input sensitivity control, providing three different sen-
sitivity settings. High input sensitivity allows for signifi-
cant amounts of flat loss or for use with input signals
at the monitor level. Figure 1 shows the block diagram
of the device.
The XRT7295AE is manufactured by using linear
CMOS technology. The XRT7295AE is available in a
20-pin plastic SOJ package for surface mounting. A pin
compatible version is available for DS3 or STS-1
applications. Please refer to the XRT7295AT data
