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.
