LMH6586  
32x16 Video Crosspoint Switch  
General Description  
Features  
The LMH6586 is a non-blocking 32x16 analog video cross-  
point switch. It can be used to route standard composite video  
signals, (NTSC and PAL) and any one of the 32 inputs can  
be routed to any one of the 16 outputs. The LMH6586 can  
operate in broadcast mode as well as individual mode. The  
outputs have programmable 1X or 2X gain output buffers and  
can drive loads of 150. Each input has an integrated DC-  
restore clamp for AC-coupled operation.  
32x16 Non-blocking Switch with buffered inputs and  
outputs.  
100 kHz I2C compatible interface  
Individually addressable outputs  
Input video clamp  
Selectable output buffer gain (+1V/V or +2V/V)  
−3 dB Bandwidth = 66 MHz  
DG = 0.05%, DP = 0.05° @ RL = 150Ω  
−70 dB off-isolation @ 6 MHz  
I2C compatible interface with 2-bit programmable slave  
address  
The LMH6586 operates from a common single +5V supply for  
its analog sections as well as its digital logic and I2C interface.  
The LMH6586 also has two types of input signal detection  
ideal for security camera monitoring. It can be configured to  
output a flag upon the loss of sync with an external voltage  
control pin used to set the sync detection threshold level. It  
can also be configured to output a flag upon the detection of  
presence or absence of video with an 8-level programmable  
video detection threshold.  
Single +5V supply operation  
Input and output amp power shutdowns  
Video detect with 8 adjustable programmable threshold  
level  
The crosspoint switch matrix configuration is programmed via  
a 100 kHz I2C compatible interface. The device address is 2-  
bit programmable, accommodating up to four LMH6586’s on  
a common I2C bus, facilitating expansion of the Crosspoint  
matrix.  
Sync detect with adjustable programmable threshold level  
Extra video output for external sync separator (OUT16)  
Applications  
CCTV security systems  
The LMH6586 is offered in a space-saving 80-pin TQFP.
