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 equalization (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 sensitivity settings. High input sensitivity allows for significant amounts of flat loss or for use with input signals at the monitor level. Figure 1 shows the block diagram of the device.
