LMH6582 16x8 550 MHz Analog Crosspoint Switch, Gain of 1
LMH6582 16x8 550 MHz Analog Crosspoint Switch, Gain of 1
February 2007
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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications, see the Electrical Characteristics tables.
Note 2: Human Body Model, applicable std. MIL-STD-883, Method 3015.7. Machine Model, applicable std. JESD22-A115-A (ESD MM std. of JEDEC)
Field-Induced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC).
Note 3: The maximum output current (I
Note 4: The maximum power dissipation is a function of T
PD = (T
Note 5: Electrical Table values apply only for factory testing conditions at the temperature indicated. No guarantee of parametric performance is indicated in the electrical tables under conditions different than those tested.
Note 6: Slew Rate is the average of the rising and falling edges.
Note 7: Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will
also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material.
Note 8: Room Temperature limits are 100% production tested at 25°C. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control (SQC) methods.
Note 9: Negative input current implies current flowing out of the device.
Note 10: Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
Note 11: This parameter is guaranteed by design and/or characterization and is not tested in production.
