DATASHEET EL4543 FN7325 Rev 11.00 Triple Differential Twisted-Pair Driver with Common-Mode Sync Encoding September 13, 2007 The EL4543 is a high bandwidth triple differential amplifier Features with integrated encoding of video sync signals. The inputs Fully differential inputs, outputs, and feedback are suitable for handling high speed video or other communications signals in either single-ended or differential 350MHz -3dB bandwidth form, and the common-mode input range extends all the way 1200V/s slew rate to the negative rail enabling ground-referenced signalling in -75dB distortion at 5MHz single supply applications. The high bandwidth enables differential signalling onto standard twisted-pair or coax with Single 5V to 12V operation very low harmonic distortion, while internal feedback 50mA minimum output current ensures balanced gain and phase at the outputs reducing radiated EMI and harmonics. Low power - 36mA total typical supply current Embedded logic encodes standard video horizontal and Pb-free available (RoHS compliant) vertical sync signals onto the common mode of the twisted Applications pair(s), transmitting this additional information without the requirement for additional buffers or transmission lines. The Twisted-pair drivers EL4543 enables significant system cost savings when Differential line drivers compared with discrete line driver alternatives. VGA over twisted-pair The EL4543 is available in both a 24 Ld QSOP package and a 20 Ld QFN package and is specified for operation over the Transmission of analog signals in a noisy environment -40C to +85C temperature range.
