LMH6570

2:1 High Speed Video Multiplexer

General Description

Features

n 500 MHz, 500 mV_PP, −3 dB bandwidth, A_V=2

n 400 MHz, 2V_PP, −3 dB bandwidth, A_V=2

n 8 ns channel switching time

™

The LMH 6570 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 band-

width at 2 V_PPoutput signal levels. Multimedia and high

definition television (HDTV) applications can benefit from the

LMH6570’s 0.1 dB bandwidth of 150 MHz and its 2200 V/µs

slew rate.

n 70 dB channel to channel isolation 10 MHz

n 0.02%, 0.05˚ diff. gain, diff. phase

n 0.1 dB gain flatness to 150 MHz

n 2200 V/µs slew rate

n Wide supply voltage range: 6V ( 3V) to 12V ( 6V)

n −68 dB HD2 5 MHz

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

n −84 dB HD3 5 MHz

75Ω load. An 80 mA linear output current is available for Applications

driving multiple video load applications.

n Video router

The LMH6570 gain is set by external feedback and gain set

resistors for maximum flexibility.

n Multi input video monitor

n Instrumentation / Test equipment

n Receiver IF diversity switch

n Multi channel A/D driver

n Picture in Picture video switch

The LMH6570 is available in the 8 pin SOIC package.
