3 Description

The LMH6570 is a high performance analog

multiplexer optimized for professional grade video

and other high fidelity, high bandwidth analog

applications. The output amplifier selects one of two

buffered input signals based on the state of the SEL

pin. The LMH6570 provides a 400 MHz bandwidth at 2-VPP output signal levels. Multimedia and high

definition television (HDTV) applications can benefit

from the 0.1-dB bandwidth of 150 MHz and the 2200-

V/μs slew rate of LMH6570.

The LMH6570 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 LMH6570 gain is set by external feedback and

gain set resistors for maximum flexibility.

The LMH6570 is available in the 8-pin SOIC

package.
