The MAX4357 is a 32 16 hig hly inte g ra te d vid e o  
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 75reverse-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-  
a b le d s ta te to a void outp ut c onflic ts in la rg e -a rra y  
configurations.

0.1dB Gain Flatness to 12MHz  
Minimum -62dB Crosstalk, -110dB Isolation at

0.05%/0.1° Differential Gain/Differential Phase  
Superior flexibility, high integration, and space-saving  
packaging make this nonblocking switch matrix ideal  
for routing vid e o s ig na ls in s e c urity a nd vid e o-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.
