Intersil's Adaptive Composite Video Equalizer - First Ever Device to Deliver Picture-Perfect Images Up to 1.67km (1 mile) Over Cat 5 or Coaxial Cable

These industry-best adaptive equalizers enable cameras or video displays to be placed in remote areas, eliminating the need for repeaters and distribution hubs, making the family ideal for the security market or any application using composite video. In addition to its remarkable performance, the MegaQ family requires no user interaction or adjustments to get the best performance, so video quality is no longer dependent on the installer.

Adaptive equalization takes place on the receive end of the signal chain where images are viewed, so a MegaQ equalizer can easily be added to existing installations, instantly improving image quality. MegaQ does not require any active circuitry at the transmission (or camera) end, so cameras already at remote sites or mounted on buildings or poles do not need to be retrofitted. The ISL59605 compensates for high frequency cable loss up to 60dB at 5MHz, as well as source amplitude variations up to ±3dB.

Every device is automatically compatible with NTSC and PAL, color and monochrome, with no hidden caveats. Inputs are AC-coupled and internally DC-restored to maximize common mode noise rejection. The output can drive 2VP-P into two source-terminated 75? loads. The equalizers require a single +5V supply and consume only 500mW.

The MegaQ family continuously monitors the cable characteristics and compensates for long-term cable aging. Several optional locking modes are available to help maintain lock in noisy environments. An optional serial interface on each device provides signal monitoring.
