LMH6582
16x8 550 MHz Analog Crosspoint Switch, Gain of 1
General Description
The LMH^® family of products is joined by the LMH6582, a high
speed, non-blocking, analog, crosspoint switch. The
LMH6582 is designed for high speed, DC coupled, analog
signals like high resolution video (UXGA and higher). The
LMH6582 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 LMH6582 can be impedance matched to nearly any
source impedance. The buffered outputs of the LMH6582 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 LMH6582 is controlled with a 4 pin serial inter-
face. Both single serial mode and addressed chain modes are
available.
The LMH6582 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. The package has an exposed thermal
pad on the bottom of the package.
