LMH6580, LMH6581 www.ti.com SNOSAY4C – AUGUST 2007 – REVISED MAY 2013 LMH6580/LMH6581 8x4 500 MHz Analog Crosspoint Switch, Gain of 1, Gain of 2 Check for Samples: LMH6580, LMH6581 FEATURES DESCRIPTION • • • The LMH™ family of products is joined by the LMH6580 and the LMH6581, high speed, nonblocking, 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. 1 23 • • • • • • • • • 8 Inputs and 4 Outputs 48-pin TQFP Package −3 dB Bandwidth (VOUT = 2 VPP, RL = 1 kΩ) 500 MHz −3 dB Bandwidth (VOUT = 2 VPP, RL = 150Ω) 450 MHz Fast Slew Rate 2100 V/μs Channel to Channel Crosstalk (10/100 MHz) −70/ −52 dBc All Hostile Crosstalk (10/100 MHz) −55/−45 dBc Easy to Use Serial Programming 4 Wire Bus Two Programming Modes Serial & Addressed Modes Symmetrical Pinout Facilitates Expansion.

The maximum output current (IOUT) is determined by device power dissipation limitations. The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – TA)/ θJA. All numbers apply for packages soldered directly onto a PC Board.

No ensured parametric performance is indicated in the electrical tables under conditions different than those tested. 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 specified through correlation using Statistical Quality Control (SQC) methods. 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 specified on shipped production material.
