LMH6584/LMH6585

32x16 400 MHz Analog Crosspoint Switches, Gain of 1,

Gain of 2

General Description

Features

The LMH^®family of products is joined by the LMH6584 and

the LMH6585 high speed, non-blocking, analog, crosspoint

switches. The LMH6584/LMH6585 are designed for high

speed, DC coupled, analog signals such as high resolution

video (UXGA and higher). The LMH6584/LMH6585 have 32

inputs and 16 outputs. The non-blocking architecture allows

an output to be connected to any input, including an input that

is already selected. With fully buffered inputs the LMH6584/

LMH6585 can be impedance matched to nearly any source

impedance. The buffered outputs of the LMH6584/LMH6585

can drive up to two back terminated video loads (75Ω load).

The outputs and inputs also feature high impedance inactive

states allowing high performance input and output expansion

for array sizes such as 32 x 32 or 64 x 16 by combining two

devices. The LMH6584/LMH6585 are controlled with a 4 pin

serial interface. Both single serial mode and addressed chain

modes are available.
