4:1 High Speed Video Multiplexer
General DescriptionThe LMH™6574isa high performance analog multiplexer
optimizedfor professional grade video and other high fidelity
high bandwidth analog applications. The output amplifier
selects any oneof four buffered input signals basedon the
stateofthe two address bits. The LMH6574 providesa 400
MHz bandwidthat2 VPP output signal levels. Multimedia and
high definition television (HDTV) applications can benefit
fromthe LMH6574’s 0.1dB bandwidthof 150 MHz andits
2200 V/µs slew rate.
The LMH6574 supports composite video applications withits
0.02% and 0.05˚ differential gain and phase errorsfor NTSC
and PAL video signals while drivinga single, back terminated
75Ω load.An80 mA linear output currentis availablefor
driving multiple video load applications.
The LMH6574 gainissetby external feedback and gainset
resistorsfor maximum flexibility.
The LMH6574is availablein the14pin SOIC package.
