The AD8122 is a triple, high speed, differential receiver and equalizer that compensates for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Each channel features a high impedance differential input that is ideal for interfacing directly with the cable.The AD8122 has two control inputs for optimal cable compensation, one LPF control input, an input to select between UTP and coax cable, and an output offset adjust input. The cable compensation inputs are used to compensate for different cable lengths; the VPEAK input controls the amount of high frequency peaking and the VGAIN input adjusts the broadband flat gain, which compensates for the flat cable loss. The VFILTER input controls the cutoff frequency of output lowpass filters on each channel. Selection between UTP and coaxial cable compensation responses is determined by the binary COAX/UTP?input, which can be left floating in UTP applications. The VOFFSET pin allows the dc voltage at the output to be adjusted, which can be useful in dc-coupled systems.For added flexibility, the gains of each channel can be set to x1 or x2 using the associated GAIN control pins.The AD8122 is available in a 6 mm ? 6 mm, 40-lead LFCSP and is rated to operate over the extended temperature range of ?40?C to +85?C.APPLICATIONS Keyboard-video-mouse (KVM) Digital signage RGB video over UTP cables Professional video projection and distribution HD video Security video

The AD8124 is a triple, high speed, differential receiver and equalizer that compensates for the transmission losses of UTP and coaxial cables up to 200 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry inside the AD8124 controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths.

Each channel features a high impedance differential input that is ideal for interfacing directly with the cable.The AD8124 has three control pins for optimal cable compensation, as well as an output offset adjust pin. Two voltage-controlled pins are used to compensate for different cable lengths; the VPEAK pin controls the amount of high frequency peaking and the VGAIN pin adjusts the broadband flat gain, which compensates for the low frequency flat cable loss.For added flexibility, an optional pole adjustment pin, VPOLE, allows movement of the pole locations, allowing for the compensation of different gauges and types of cable as well as variations between different cables and/or equalizers. The VOFFSET pin allows the dc voltage at the output to be adjusted, adding flexibility for dc-coupled systems.The AD8124 is available in a 6 mm ? 6 mm, 40-lead LFCSP and is rated to operate over the extended temperature range of ?40?C to +85?C.APPLICATIONS Keyboard-video-mouse (KVM) Digital signage RGB video over UTP cables Professional video projection and distribution HD video Security video
