2:1 High Speed Video Multiplexer
General DescriptionThe LMH™6570isa high performance analog multiplexer
optimizedfor professional grade video and other high fidelity
high bandwidth analog applications. The output amplifier
selects oneof two buffered input signals basedonthe state the SEL pin. The LMH6570 providesa 400 MHz band-
widthat2 VPP output signal levels. Multimedia and high
definition television (HDTV) applications can benefit fromthe
LMH6570’s0.1dB bandwidthof 150 MHz andits 2200 V/µs
slew rate.
The LMH6570 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 LMH6570 gainissetby external feedback and gainset
resistorsfor maximum flexibility.
The LMH6570is availablein the8pin SOIC package.
