DATASHEET ISL59311 FN6372 Rev 3.00 Differential Video Amplifier with Common Mode Sync Encoder and Serial Digital April 25, 2007 Interface The ISL59311 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 650MHz -3dB bandwidth form, and the common-mode input range extends The 1500V/s slew rate ISL59311 is a high bandwidth triple differential amplifier with -70dB distortion at 20MHz integrated encoding of video sync signals. The inputs are suitable for handling high speed video or other Single 5V operation communications signals in either single-ended or differential 50mA minimum output current form, and the common-mode input range extends all the way to the negative rail enabling ground-referenced signaling in Low power: 57mA total supply current single supply applications. The high bandwidth enables Pb-free plus anneal available (RoHS compliant) differential signaling onto standard twisted-pair or coax with very low harmonic distortion, while internal feedback Block Diagram ensures balanced gain and phase at the outputs reducing radiated EMI and harmonics. V V CCA CCD Embedded logic encodes standard video horizontal and V domain CCA vertical sync signals onto the common mode of the twisted V A+ IN + VOUTA+ pair(s), transmitting this additional information without the - VINA- VOUTA- requirement for additional buffers or transmission lines. The Disable ISL59311 enables significant system cost savings when compared with discrete line driver alternatives. V B+ + V B+ IN OUT The digital block of the chip is a data transceiver which is V B- V B- IN - OUT intended to drive one twisted pair line. The maximum CM A HSYNC baudrate for this block is 50Mbps.
