The EL4543 is a high bandwidth triple differential amplifierwith integrated encoding of video sync signals. The inputsare suitable for handling high speed video or othercommunications signals in either single-ended or differentialform, and the common-mode input range extends all the wayto the negative rail enabling ground-referenced signalling insingle supply applications. The high bandwidth enablesdifferential signalling onto standard twisted-pair or coax withvery low harmonic distortion, while internal feedbackensures balanced gain and phase at the outputs reducingradiated EMI and harmonics.Embedded logic encodes standard video horizontal andvertical sync signals onto the common mode of the twistedpair(s), transmitting this additional information without therequirement for additional buffers or transmission lines. TheEL4543 enables significant system cost savings whencompared with discrete line driver alternatives.
