Intersil EL4543IU

ДрайверДифференциальный350 МГц

Overview

The EL4543IU is a high bandwidth triple differential amplifier with integrated encoding of video sync signals. The inputs are suitable for handling high speed video or other communications signals in either single-ended or differential form, and the common-mode input range extends all the way to the negative rail enabling ground-referenced signalling in single supply applications. The high bandwidth enables differential signalling onto standard twisted-pair or coax with very low harmonic distortion, while internal feedback ensures balanced gain and phase at the outputs reducing radiated EMI and harmonics. Embedded logic encodes standard video horizontal and vertical sync signals onto the common mode of the twisted pair(s), transmitting this additional information without the requirement for additional buffers or transmission lines. The EL4543IU enables significant system cost savings when compared with discrete line driver alternatives. The EL4543IU is available in both a 24 Ld QSOP package and a 20 Ld QFN package and is specified for operation over the -40°C to +85°C temperature range.
