The ISL59601, ISL59602, ISL59603, ISL59604, and ISL59605 (the “MegaQ™” product family) are single-channel adaptive equalizers designed to automatically compensate for long runs of Cat 5/6 or RG-59 cable, producing high quality video output with no user interaction. The ISL59601 equalizes Cat 5/6 up to a distance of 1000 feet (300 meters), while the ISL59605 equalizes up to 5300 feet (1600 meters). MegaQ™ compensates for high frequency cable losses of up to 60dB (ISL59605) at 5MHz as well as source amplitude variations up to ±3dB. The ISL59601, ISL59602, ISL59603, ISL59604, and ISL59605 operate from a single +5V supply. Inputs are AC-coupled and internally DC-restored. The output can drive 2VP-P into two source-terminated 75Ω loads (AC-coupled or DC-coupled).
