250MHz Triple Differential Receiver/ Equalizer with I2C
Interface
ISL59911
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.
