ISL59311 Differential Video Amplifier with Common Mode Sync Encoder and Serial Digital Interface 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. Applications • Twisted-pair drivers • Differential line drivers • VGA over twisted-pair • Transmission of analog signals in a noisy environment Features • Fully differential inputs, outputs, and feedback • 650MHz -3dB bandwidth • 1500V/µs slew rate • -70dB distortion at 20MHz • Single 5V operation • 50mA minimum output current • Low power: 57mA total supply current • Pb-free plus anneal available (RoHS compliant) Block Diagram Ordering Information PART NUMBER (Note) PART MARKING TAPE & REEL PACKAGE (Pb-Free) PKG.
