General Description
The MAX4358 is a 32
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 sin-
gle +5V supply. Digital logic is supplied from an inde-
pendent single +2.7V to +5.5V supply. Individual
outputs can be switched between an input video signal
source and OSD information through an internal, dedi-
cated 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 75
reverse-terminated video loads.
The switch matrix configuration and output buffer gain
are programmed through an SPI/QSPI-compatible,
three-wire serial interface and initialized with a single
update signal. The unique serial interface operates in
two modes facilitating both fast updates and initializa-
tion. On power-up, all outputs are initialized in the dis-
abled 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 MAX4358 is available in a 144-pin TQFP package
and specified over an extended -40°C to +85°C tem-
perature range. The MAX4358 evaluation kit is available
to speed designs.
