General Description
The MAX4357 is a 32 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 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 MAX4357 is available in a 128-pin TQFP package
and specified over an extended -40°C to +85°C tem-
perature range.
