General Description

The MAX9132/MAX9134/MAX9135 high-speed, multi-

ple-port, low-voltage differential signaling (LVDS) cross-

bar switches are specially designed for digital video

and camera signal transmission. These switches have a

wide bandwidth, supporting data rates up to 840Mbps.

The MAX9132 has three input ports and two output

ports, the MAX9134 has three input ports and four out-

put ports, and the MAX9135 has four input ports and

three output ports. The digital video or camera signal

can go through the switches from an input port to one

or multiple output ports.

The MAX9132/MAX9134/MAX9135 switch routing is

programmable through either an I

C interface or a

Local Interconnect Network (LIN) serial interface. In

addition, the MAX9134/MAX9135 provide pins to set

switch routing. These pins also set the initial conditions

for the I

C mode. To generate more input or output

ports, these switches can be connected in parallel or in

cascade.

The MAX9132/MAX9134/MAX9135 operate from a

+3.3V supply and are specified over the -40°C to

+105°C temperature range. The MAX9134/MAX9135

are available in a 32-pin (5mm x 5mm) TQFP package,

while the MAX9132 is available in a 20-pin (6.5mm x

4.4mm) TSSOP package. The input/output port pins are

rated up to ±25kV ESD for the ISO Air-Gap Discharge

Model, ±15kV ESD for the IEC Air-Gap Discharge

Model, and ±10kV for the ESD Contact Discharge

Model. All other pins support up to ±3kV ESD for the

Human Body Model.
