Overview
Description
The ISL59911 is a triple channel differential receiver and equalizer optimized for RGB and YPbPr video signals. It contains three high speed differential receivers with programmable frequency compensation. The ISL59911 features manual or automatic offset calibration and ±4dB of gain adjustment range with a resolution of 0. 1dB. The ISL59911 has a bandwidth of 250MHz and consumes only 110mA from a ±5V supply in normal operation. When deasserted, the ENABLE pin puts the amplifiers into a low power, high impedance state, minimizing power when not needed and also allowing multiple devices to be connected in parallel, allowing two or more ISL59911 devices to function as a multiplexer. The ISL59911 can also directly decode the sync signals encoded onto the common modes of three pairs of Cat 5 cable (by an ISL59311, EL4543, or similar device) or it can output the actual common mode voltages for each of the three channels. The ISL59911 is available in a 32 Ld QFN package and is specified for operation over the full -40°C to +85°C temperature range.
