GENERAL DESCRIPTION  
The XR-T7295 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. (See  
Figure 13).  
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 XR-T7295 device is manufactured using linear  
CMOS technology. The XR-T7295 is available in either a  
20-pin plastic DIP or 20-pin plastic SOJ package for  
surface mounting.  
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  
Two versions of the chip are available, one is for either  
DS3 or STS-1 operation (the XR-T7295, this data sheet),  
and the other is for E3 operation (the XR-T7295E, refer to  
the XR-T7295E 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.
