your ? electronic ? engineering ? resource ? ? xrt7295at ds3 sonet sts1 integrated line receiver general description: the xrt7295at ds3/sonet sts-1 integrated line receiver is a fully integr ated 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), autom atic-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 cr oss-connect frame to the device. t he receive input has a variable input sensitivity control, providing three di fferent sensitivity settings, to adapt longer cables. high input sensitivity allows for significant amounts of flat loss within the system. figure 1 shows the block diagr am of the device. the xrt72 95at 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 legal disclaimer: the content of the pages of this website is for your general information and use only . it is subject to change without notice. from time to time, this website may also include links to other websites. these links are provided for your convenience to provide further information. they do not signify that we endorse the website(s). we have no responsibility for the content of the linked we bsite(s). your use of any information or materials on this website is entirely a t your own risk, for which we shall not be liable. it shall be your own responsibility to ensure that any products, services or information availa ble through this website meet your specif ic requirements.
