3 Description
The LMH6572 is a high performance analog
multiplexer optimized for professional grade video
and other high fidelity, high bandwidth analog
applications. The LMH6572 provides a 290-MHz
bandwidth at 2-VPP output signal levels. The 140 MHz
of 0.1-dB bandwidth and a 1500-V/μs slew rate make
this part suitable for high definition television (HDTV)
and high resolution multimedia video applications.
The LMH6572 supports composite video applications
with its 0.02% and 0.02° differential gain and phase
errors for NTSC and PAL video signals while driving
a single, back terminated 75-Ω load. The LM6572
can deliver 80-mA linear output current for driving
multiple video load applications.
The LMH6572 has an internal gain of 2 V/V (+6 dBv)
for driving back terminated transmission lines at a net
gain of 1 V/V (0 dBv).
The LMH6572 is available in the SSOP package.
