XRT7295AT DS3 SONET STS1 Integrated Line Receiver
General Description:
The XRT7295AT DS3/SONET STS-1 integrated line
receiver is a fully integrated receive interface that
terminates a bipolar DS3 (44.736Mbps) or Sonet STS-1
(51.84Mbps) signal transmitted over coaxial cable.
The device also provides the functions of receive
equalization (optional), automatic-gain control (AGC),
clock-recovery and data retiming, loss-of-signal and
loss-of-frequency-lock
detection.
The
digital
system
interface is 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
distances of 0 to 450ft. from the cross-connect frame to the device. The receive input has a variable input
sensitivity control, providing three different sensitivity settings, to adapt longer cables. High input sensitivity
allows for significant amounts of flat loss within the system.
Figure 1
shows the block diagram of the device.
The XRT7295AT device is manufactured using
linear CMOS technology. The XRT7295AT is
available in a 20-pin plastic SOJ package for
surface mounting. Two versions of the chip are
available, one is for either DS3 or STS-1
operation (the XRT7295AT, this data sheet),
and
the
other
is
forE3
operation
(the
XRT7295AE, refer to the XRT7295AE data
sheet). Both versions are pin compatible. For
either DS3 or STS-1, an input reference clock
at 44.736MHz or 51.84MHz provides the
frequency reference for the device.
Key Features:
Fully Integrated Receive Interface for DS3 and
STS-1 Rate Signals
