Analog Devices Introduces Industry’s Fastest and Most Power Efficient 300 meter UTP Cable Equalizer for Analog Video Distribution

The AD8122 enables clear transmission of UXGA and 1080p images over Cat-5 cables up to 300 m long.

  • Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, today introduced an integrated triple differential receiver and adjustable cable equalizer with the industry’s highest equalized bandwidth at 300 meters and the lowest power consumption. Designed for use in high-resolution analog video distribution systems, the AD8122 provides 60 MHz of equalized bandwidth, with a low 16-mV rms noise and a short settling time of only 70 ns to 1% at the maximum cable length of 300 meters. The high speed and fast settling time enable UXGA and 1080p video to be transmitted over long distances while maintaining excellent image sharpness and clarity. This high performance is achieved while consuming only 0.93 W, allowing the AD8122 to draw 13 percent less power than the nearest competitor. Applications for this high-performance cable equalizer include KVM (keyboard-video-mouse), digital signage and professional video projection/distribution.
