250MHz Triple Differential Receiver/ Equalizer with I
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.

... A 10μF capacitor on each of the V+ and V- supplies provides sufficient low-frequency decoupling. The 10μF capacitors do not need to be particularly close to the ISL59911 to be effective, but should still have a low-impedance path to the supply rails. In many mixed-signal ICs, separation of the analog and digital supplies and grounds is critical to prevent digital noise from appearing on the analog signals ...

... When the ISL59911 is first powered up, the offset error is undefined until an offset calibration is performed. The output offset voltage of the ISL59911 also varies as the filter and gain settings are adjusted. To minimize offset, always perform an offset calibration after finalizing the filter and gain settings. ...

... Power Dissipation The ISL59911 is designed to operate with ±5V supply voltages. The supply currents are tested in production and guaranteed to be less than 140mA per channel. Operating at ±5V power supply, the total power dissipation is shown by Equation 1: × × MAX S SMAX ...

... The bus is nominally inactive, with SDA and SCL high. Communication begins when the host issues a START command by taking SDA low while SCL is high (Figure 14). The ISL59911 continuously monitors the SDA and SCL lines for the start condition and does not respond to any command until this condition has been met ...
