LMH6572
Triple 2:1 High Speed Video Multiplexer
General Description
The LMH™6572 is a high performance analog mulitplexer
optimized for professional grade video and other high fidelity
high bandwidth analog applications. The LMH6572 provides
a 290MHz bandwidth at 2 V_PP output signal levels. The 140
MHz of .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
75Ω load. The LMH6572 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.
