LMH6582 Datasheet | National Semiconductor

Description The LMH™ family of products is joined by the LMH6582/ LMH6583, a high speed, non-blocking, analog, crosspoint switch. The LMH6582 has a gain of 1 while the LMH6583 has a gain of two. The LMH6582/ LMH6583 is designed for high speed, DC coupled, analog signals like high resolution video (UXGA and higher). The LMH6582/ 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 LMH6582/ LMH6583 can be impedance matched to nearly any source impedance. The buffered outputs of the LMH6582/ LMH6583 can drive up to two back terminated video loads (75 Ohm 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 bining two devices. The LMH6582/ LMH6583 is controlled with a 4 pin serial interface. Both single serial mode and addressed chain modes are available. The LMH6582/ LMH6583 es in a 64- pin thermally enhanced TQFP package. It also has diagonally symmetrical pin assignments to facilitate double sided board layouts and easy pin connections for expansion. The package has an exposed thermal pad on the bottom of the package.
