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

Analog Devices has introduced an integrated triple differential receiver and adjustable cable equalizer with high equalized bandwidth at 300 m and the low power consumption. Designed for 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 m. The high speed and fast settling time enable transmission of UXGA and 1080p video over long distances while maintaining excellent image sharpness and clarity. The AD8122 achieves this high performance while consuming only 0.93 W, allowing the IC to draw 13% less power than the nearest competitor. Applications for this high-performance cable equalizer include KVM (keyboard-video-mouse), digital signage, and professional video projection and distribution. AD8122 Key Features and Benefits

  • High speed with fast settling provides excellent image sharpness and clarity
  • Integrated adjustable LPF (low pass filter) minimizes board space and reduces design time needed to optimize image quality
  • Equalization for both Cat-5 and coaxial cables
  • Compatible with RGB and VGA display resolutions up to UXGA and 1080p
Pricing, Availability and Complementary Products The AD8122 is available now in a 40-lead LFCSP package. Rated for operating temperatures of -40 to 85 °C, the AD8122 is priced at $9.90 in quantities of 1000 units. Complementary components include ADI's AD8120 video delay line and AD8146/7/8 triple differential drivers for implementing a high-performance analog video over Cat-5 cable extender system.
