Providing a bandwidth of over 240MHz and a slew rate of 450V/us, the ZXFV301 and ZXFV302 multiplexer chips from Zetex serve a broad range of video and other high-speed signal switching applications. Now available from 2001 Electronic Components, the ZXFV301/2 are 4:1 multiplexers, characterised for use with 400pF loads. Its stability and high - 40mA - output current capability handles 75ohm cable driving and high performance video circuits.
Low differential gain and phase distortion - 0.01% and 0.04 degrees, respectively - makes this device suitable for high-quality video switching.
Operation is simple.
Input channel selection is by means of an individual channel select pin for the ZXFV301 or a two-bit input for the ZXFV302.
An additional output enable line allows ZXFV301/2 to be cascaded; two chips for example creating a low-cost eight-channel CCTV solution.
Presented in a 16-pin surface mount package, this high speed multiplexer IC needs a +/-5V supply and a supply current of 17mA.
The ZXFV301/2 will find applications in video routing and switching, CCTV switching, RGB multiplexing and switching in other high-frequency instrumentation.
The ZXFV301/2 is the latest addition to Zetex's rapidly expanding signal management product family.
