GENERALDESCRIPTION

TheXRT7295AEE3IntegratedLineReceiverisafully

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),

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.

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

The XRT7295AE is manufactured by using linear

CMOS technology. The XRT7295AE is available in a

20-pinplasticSOJpackageforsurfacemounting.Apin

compatible version is available for DS3 or STS-1

applications. Please refer to the XRT7295AT data
