Features 32 inputs and 16 outputs AC-coupled inputs with integrated DC restore clamp Individually addressable outputs Pin-selectable output buffer gain (1 V/V or 2 V/V) –3 dB bandwidth = 66 MHz DG = 0.05%, DP = 0.05° @ RL = 150Ω, AV = 2V/V −70 dB off-isolation @ 6 MHz Individual input and output shutdown modes Device power down mode Video detection with programmable threshold (8 levels) Sync detection with pin-configurable threshold 100 kHz I 2C interface with 2-bit configurable slave address Single 5V supply operation Extra video output (VOUT_16) for external video sync separator Description The LMH6586 is a non-blocking analog video crosspoint switch designed for routing standard NTSC or PAL composite video signals. The non-blocking architecture allows any of the 32 inputs to be connected to any of the 16 outputs, including any input that is already connected. Each input has an integrated DC restore clamp for biasing of the AC-coupled video signal. The output buffers have a common selectable gain setting of 1X or 2X and can drive loads of 150Ω. The LMH6586 features two types of input signal detection for convenient monitoring of activity on any input channel. Video detection can be configured to indicate when either “presence of video” or “loss of video” is detected across the video threshold level controlled by a programmable register. Additionally, sync detection can be configured to indicate when “loss of sync” is detected across the sync threshold level controlled by a DC voltage input. The switch configuration and other parameters are programmable via the I 2C bus interface. The slave device address is configurable via two external pins allowing up to four LMH6586 devices, each with a unique address, on a common I 2C bus. This helps facilitate expansion of the crosspoint matrix array size (e.g. 64 x 16). The LMH6586 operates from a common single 5V supply for its analog sections as well as its control logic and I 2C interface. The LMH6586 is offered in a space-saving 80-pin TQFP.

Description: The LMH6586 evaluation board platform was designed by National Semiconductor to demonstrate the performance of the LMH6586 analog video Crosspoint switch. The evaluation platform consists of the LMH6586 evaluation board and a USB interface board, and can be controlled from a PC using Nationals LMH6586 evaluation software. The board provides 32 BNC inputs to apply Composite video signals (NTSC and PAL) and 17 BNC video signal outputs. Headers and test points are provided to access other important signals. The external potentiometers on the board are provided to adjust the sync detect threshold and clamp voltage. The on-board jumpers can be used to control various functions such as chip id, device reset and power save of the LMH6586.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
