The MAX9675 is a nonblocking 16 x 16 video crosspoint switch with buffered inputs and outputs. The device operates on ±5V analog supplies. Digital logic is supplied separately from an independent +2.7V to +5V supply. The MAX9675 inputs and outputs are buffered with all outputs able to drive a standard 75Ω reverse-terminated video load.
The switching matrix and programmable gain are controlled through an SPI™/QSPI™-compatible 3-wire serial interface. The serial interface is designed to operate in either of two modes to provide fast updates and initialization. All outputs are held in the disabled state during power-up to avoid signal conflicts in large switching arrays.
The programmability and high level of integration make the MAX9675 an ideal choice for nonblocking video switch arrays in security, surveillance, and video-on-demand systems.
The MAX9675 is available in a 100-pin TQFP package and specified over the extended -40°C to +85°C temperature range.
