LMH6583

16x8 550 MHz Analog Crosspoint Switch, Gain of 2

General Description

Features

The LMH^®family of products is joined by the LMH6583, a high

speed, non-blocking, analog, crosspoint switch. The

LMH6583 is designed for high speed, DC coupled, analog

signals like high resolution video (UXGA and higher). The

LMH6583 has 16 inputs and 8 outputs. The non-blocking ar-

chitecture allows an output to be connected to any input,

including an input that is already selected. With fully buffered

inputs the LMH6583 can be impedance matched to nearly any

source impedance. The buffered outputs of the LMH6583 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 16 x 16 or 32 x 8 by combining two

devices. The LMH6583 is controlled with a 4 pin serial inter-

face. Both single serial mode and addressed chain modes are

available.

■

The LMH6583 comes in a 64-pin thermally enhanced TQFP

package. It also has diagonally symmetrical pin assignments

to facilitate double sided board layouts and easy pin connec-

tions for expansion.
