The MAX9132/MAX9134/MAX9135 high-speed, multiple-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 output 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 I²C 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 I²C 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.
