DESCRIPTION

The LMH™ family of products is joined by the

LMH6580 and the LMH6581, high speed, non-

blocking, analog, crosspoint switches. The

LMH6580/LMH6581 are designed for high speed, DC

coupled, analog signals such as high resolution video

(UXGA and higher). The LMH6580/LMH6581 each

has eight inputs and four outputs. The non-blocking

architecture allows any output to be connected to any

input, including an input that is already selected. With

fully buffered inputs the LMH6580/LMH6581 can be

impedance matched to nearly any source impedance.

The buffered outputs of the LMH6580/LMH6581 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 8

x 8 or 16 x 4 by combining two devices. The

LMH6580/LMH6581 are controlled with a 4 pin serial

interface that can be configured as a 3 wire interface.

Both serial mode and addressed modes are

available.

The LMH6580/LMH6581 come in 48-pin TQFP

packages. They also have diagonally symmetrical pin

assignments to facilitate double sided board layouts

and easy pin connections for expansion.
