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.
