LMH6582

LMH6582 16x8 550 MHz Analog Crosspoint Switch, Gain of 1 August 2007 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 architecture 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 interface. 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 connections for expansion. The package has an exposed thermal pad on the bottom of the package.
