DATASHEET ISL59911 FN7548 Rev 0.00 250MHz Triple Differential Receiver/ Equalizer with I2C Interface September 2, 2011 The ISL59911 is a triple channel differential receiver and Features equalizer optimized for RGB and YPbPr video signals. It 250MHz -3dB bandwidth contains three high speed differential receivers with programmable frequency compensation. The ISL59911 5 Adjustable EQ bands: 100MHz, 20MHz, 6MHz, 1MHz, and features manual or automatic offset calibration and 4dB of 200kHz gain adjustment range with a resolution of 0.1dB. 3rd-order lowpass filter at output with programmable corner The ISL59911 has a bandwidth of 250MHz and consumes only 4dB fine gain control with 0.1dB (7-bit) resolution 110mA from a 5V supply in normal operation. Offset calibration minimizes output offset voltage When deasserted, the ENABLE pin puts the amplifiers into a Decodes H and V signals embedded in common SYNC SYNC low power, high impedance state, minimizing power when not mode needed and also allowing multiple devices to be connected in 2 I C interface with four unique addresses parallel, allowing two or more ISL59911 devices to function as a multiplexer. 5V supplies 110mA The ISL59911 can also directly decode the sync signals 32 Ld 5mm x 6mm QFN package encoded onto the common modes of three pairs of Cat 5 cable (by an ISL59311, EL4543, or similar device) or it can output Applications the actual common mode voltages for each of the three KVM monitor extension channels. Digital signage The ISL59911 is available in a 32 Ld QFN package and is General-purpose twisted-pair receiving and equalization specified for operation over the full -40C to +85C temperature range.
