LMH6580/LMH6581
8x4 500 MHz Analog Crosspoint Switch, Gain of 1,
Gain of 2
General 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 (75
load). The outputs and inputs also feature
high impedance inactive states allowing high performance in-
put 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 connec-
tions for expansion.
