LMH6584/LMH6585
32x16 400 MHz Analog Crosspoint Switches, Gain of 1,
Gain of 2
General Description
The LMH
the LMH6585 high speed, non-blocking, analog, crosspoint
switches. The LMH6584/LMH6585 are designed for high
speed, DC coupled, analog signals such as high resolution
video (UXGA and higher). The LMH6584/LMH6585 have 32
inputs and 16 outputs. The non-blocking architecture allows
an output to be connected to any input, including an input that
is already selected. With fully buffered inputs the LMH6584/
LMH6585 can be impedance matched to nearly any source
impedance. The buffered outputs of the LMH6584/LMH6585
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 32 x 32 or 64 x 16 by combining two
devices. The LMH6584/LMH6585 are controlled with a 4 pin
serial interface. Both single serial mode and addressed chain
modes are available.
The LMH6584/LMH6585 come in 144-pin LQFP packages.
They also have diagonally symmetrical pin assignments to
facilitate double sided board layouts and easy pin connec-
tions for expansion.

... Application Information INTRODUCTION The LMH6584/LMH6585 are high speed, fully buffered, non blocking, analog crosspoint switches. Having fully buffered inputs allow the LMH6584/LMH6585 to accept signals from low or high impedance sources without the worry of loading the signal source. The fully buffered outputs will drive 75Ω or 50Ω ...
