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.
