1 / 17 page 1 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. Features • 250MHz -3dB bandwidth • 5 Adjustable EQ bands: 100MHz, 20MHz, 6MHz, 1MHz, and 200kHz • 3rd-order lowpass filter at output with programmable corner • ±4dB fine gain control with 0.1dB (7-bit) resolution • Offset calibration minimizes output offset voltage • Decodes HSYNC and VSYNC signals embedded in common mode •I2C interface with four unique addresses • ±5V supplies @ 110mA • 32 Ld 5mm x 6mm QFN package Applications • KVM monitor extension • Digital signage • General-purpose twisted-pair receiving and equalization • High-resolution security video TWISTED-PAIR RGB VIDEO RECEIVER 74HC04 or SIMILAR TERMINATION NETWORK RIN- RIN+ ISL59911 50 50 50 1k 0.1µF GIN+ GIN- BIN+ BIN- SCL SDA SYSTEM MICRO- CONTROLLER I2C INTERFACE ISL59311 OR EL4543 TRIPLE DIFFERENTIAL VIDEO DRIVER RP RP ADDR0 ADDR1 ROUT GOUT BOUT HSOUT/RCM VSOUT/GCM BCM NC RREF GREF BREF TERMINATION NETWORK TERMINATION NETWORK UP TO 300m OF CAT X CABLE +5V ENABLE -5V +5V CBYPASS * x3 CBYPASS * x3 V+ V- and THERMAL PAD GND +5V 75 x3 ISL59920 ISL59921 ISL59922 or ISL59923 VIDEO DELAY LINE FIGURE 1.
