3 Description
The LMH6574 is a high-performance analog
multiplexer 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 VPP output signal levels. Multimedia
and high definition television (HDTV) applications can
benefit from the LMH6574 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 75-Ω 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.
