` Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe MAX4356 is a 16 ✕ 16 highly integrated video crosspoint switch matrix with input and output buffers and On-Screen Display (OSD) Insertion. This device operates from dual ±3V to ±5V supplies or from a single +5V supply. Digital logic is supplied from an independent single +2.7V to +5.5V supply. Individual outputs can be switched between an input video signal source and OSD information through an internal, dedicated fast 2:1 mux (40ns switching times) located before the output buffer. All inputs and outputs are buffered, with all outputs able to drive standard 75Ω reverse-terminated video loads.
The switch matrix configuration and output buffer gain of MAX4356 are programmed via an SPI/QSPI™-compatible, threewire serial interface and initialized with a single update signal. The unique serial interface operates in two modes facilitating both fast updates and initialization. On power-up, all outputs are initialized in the disabled state to avoid output conflicts in large-array configurations.
Superior flexibility, high integration, and space-saving packaging make MAX4356 nonblocking switch matrix ideal for routing video signals in security and video-ondemand systems.
The MAX4356 is available in a 128-pin TQFP package and specified over an extended -40°C to 85°C temperature range.
