It incorporates all of the analog front-end components necessary to realize a complete, fully compliant short-haul E1 analog termination. These include, clock extractor, line driver/receiver, impedance matching resistors, and line transformers. The device is suitable for both 120 and 75 applications, by external hardwire control. No external components, such as crystals, inductors or transformers are required. An external clock reference is also not required. and MT9079 MT9079 E1 digital framers, as well as other commercially available E1 framers. The MH89793 MH89793 requires only a single 5 volt supply.
