your ? electronic ? engineering ? resource ? ? xrt7296 ds3 sts-1 e3 integrated line t ransmitter general description: the xrt7296 is a fully integrated pcm line driver ic intended for ds3 (44.736mbps) or e3(34.368mbp s) applications. it can also be used for transmitting sonet sts-1 (51.84mbps) signals over coaxial cable. the ic is designed to complement either xrt7295 ds3/sonet sts-1 or xrt7295e e3 integrated line receivers. the xrt7296 converts input clock and dual-rail unipolar data into ami pulses according to at&t technical advisory no. 34 or ccitt g.703 recommendations. the device provides b3zs (ds3) or hdb3 (e3) encoding functions for data to be transmitted to the line. a complimentary decoder circuit is also included in the chip for decoding received signals from an external line receiver. both encoder and decoder functions ca n be disabled independently through external control pins. in the receive direction, coding errors and bipolar violations are detected and flagged at an output pin. on-chip pulse shaper circuitry eliminates normally required external components for line equalization to meet the cross-connect template. for system leve l trouble-shooting and testing, both local and remote loop-backs are possible with the built-in loop-back circuit. the xr t7296 is manufactured using bicmos technology and is packaged in a 28-pin pdip or soj packages. the device requires a single 5v power supply and consumes a maximum power of 700mw. (line current feed + device dissipation). key features: ? fully integrated transmit interface for ds3/e3/sts-1 ? integrated pulse shaping circuit 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.
