描述 Description

The ISL59311 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 signaling in single supply applications. The high bandwidth enables differential signaling 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 ISL59311 enables significant system cost savings when compared with discrete line driver alternatives. The digital block of the chip is a data transceiver which is intended to drive one twisted pair line. The maximum baudrate for this block is 50Mbps.
The ISL59311 is available in a 32 Ld QFN package and is specified for operation over the -40°C to +85°C temperature range.
