MAX4355 16x16 Nonblocking Video Crosspoint Switch with I/O Buffers

Description

The MAX4355 is a 16 x 16 highly integrated video crosspoint switch matrix with input and output buffers. 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. 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 are programmed through an SPI™/QSPI™-compatible, 3-wire 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 this nonblocking switch matrix ideal for routing video signals in security and video-on-demand systems.

The MAX4355 is available in a 100-pin TQFP package and specified over an extended -40°C to +85°C temperature range.
