Maxim MAX9268 deserialiser with LVDS system interface

Maxim has introduced the latest member of its high-speed LVDS deserialiser family. The MAX9268 has an LVDS system interface.

When paired with a gigabit multimedia serial link serialiser such as the MAX9259 or MAX9249, the 9268 forms a complete bidirectional digital video link over a single DC-balanced twisted-pair or differential line.

The company’s differential, full-duplex control channel eliminates the need for an external CAN or LIN interface, simplifying design while saving space and reducing cost. This enables bidirectional communication with the display module, as well as programming of camera settings through a UART/I²C interface frame by frame.

The chipsets are suitable for motor vehicle applications such as sign recognition, collision avoidance, night vision and lane departure.

The devices offer programmable spread-spectrum modulation to reduce EMI. They allow isolation between the serialiser and deserialiser through AC-coupling; they provide hot-swap capability to increase fault tolerance and allow ‘on-the-fly’ frequency programming. Line-fault detection and integrated self-test features check for link integrity at system power-up.

The 9268 operates from a 3.3 V core supply and features a separate supply input for interfacing to 1.8 to 3.3 V logic levels. The device is packaged in a 7 x 7 mm, 48-pin TQFP and is fully specified over the -40 to +105°C temperature range.
