The MAX9675 is a nonblocking 16 x 16 video cross-
point 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 con-
trolled through an SPI™/QSPI™-compatible 3-wire seri-
al interface. The serial interface is designed to operate
in either of two modes to provide fast updates and ini-
tialization. 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 tem-
perature range.
