LMH6574
4:1 High Speed Video Multiplexer
General Description
The LMH
optimized for professional grade video and other high fidelity
high bandwidth analog applications. The output amplifier
selects any one of four buffered input signals based on the
state of the two address bits. The LMH6574 provides a
400 MHz bandwidth at 2 V
and high definition television (HDTV) applications can ben-
efit from the LMH6574’s 0.1 dB bandwidth of 150 MHz and
its 2200 V/µs slew rate.
The LMH6574 supports composite video applications with its
0.02% and 0.05˚ differential gain and phase errors for NTSC
and PAL video signals while driving a single, back terminated
75Ω load. An 80 mA linear output current is available for
driving multiple video load applications.
The LMH6574 gain is set by external feedback and gain set
resistors for maximum flexibility.
The LMH6574 is available in the 14 pin SOIC package.
