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.
