LMH6574

4:1 High Speed Video Multiplexer

General Description

Features

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

™

The LMH 6574 is a high performance analog multiplexer

optimized for professional grade video and other high fidelity

high bandwidth analog applications. The output amplifier

selects any one of four buffered input signals based on the

state of the two address bits. The LMH6574 provides a 400

MHz bandwidth at 2 V_PPoutput signal levels. Multimedia and

high definition television (HDTV) applications can benefit

from the LMH6574’s 0.1 dB bandwidth of 150 MHz and its

2200 V/µs slew rate.

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

n 8 ns channel switching time

n 70 dB channel to channel isolation 10 MHz

n 0.02%, 0.05˚ diff. gain, 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 LMH6574 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 LMH6574 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 LMH6574 is available in the 14 pin SOIC package.
