500MHz Triple 4:1 Gain of 2, Multiplexing Amplifier Evaluation Board


The ISL59446EVAL1/ISL59446IRZ-EVAL evaluation board contains all the circuitry needed to characterize critical performance parameters of the ISL59446 500MHz triple 4:1 MUX amplifiers over a variety of applications.

The ISL59446 contains three separate 4:1 high impedance input multiplexers, each followed by a non-inverting output current-feed amplifier set to a fixed gain of two. A common set of logic inputs is provided. Control features include a high-speed (20ns) HIZ output control for individual selection of MUX amps that share a common video output line. The ENABLE control can be used to save power by powering the device down.
