The LMH family of products is joined by
the LMH6583, a high speed, non-blocking, analog, crosspoint switch. The LMH6583 is designed for
high speed, DC coupled, analog signals like high resolution video (UXGA and higher). The LMH6583
has 16 inputs and 8 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 LMH6583 can be
impedance matched to nearly any source impedance. The buffered outputs of the LMH6583 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 LMH6583 is controlled with a 4 pin serial interface.
Both single serial mode and addressed chain modes are available.
The LMH6583 comes in a 64-pin thermally enhanced HTQFP package. It also has diagonally
symmetrical pin assignments to facilitate double sided board layouts and easy pin connections for
