Maxim introduced the latest member of its high-speed LVDS deserializer family: the MAX9268 deserializer with LVDS system interface. When paired with a gigabit multimedia serial link (GMSL) serializer such as the MAX9259 or MAX9249, the MAX9268 forms a complete bidirectional digital video link over a single DC-balanced twisted-pair or differential line. Maxim's patent-pending, differential, full-duplex control channel eliminates the need for an external CAN or LIN interface, thus simplifying design while saving space and reducing cost. This approach enables bidirectional communication with the display module, as well as programming of camera settings through a UART/I2C interface on a frame-by-frame basis. The MAX9259/MAX9268 chipset is ideal for automotive applications such as sign recognition, collision avoidance, night vision, and lane departure.

Additionally, the MAX9259/MAX9268 offer programmable spread-spectrum modulation to reduce EMI, making it easier to pass automotive compliance tests. The devices allow isolation between the serializer and deserializer through AC-coupling, they provide hot-swap capability to increase fault tolerance, and they allow on-the-fly frequency programming. Line-fault detection and integrated self-test features check for link integrity at system power-up.

The MAX9268 operates from a 3.3V core supply and features a separate supply input for interfacing to 1.8V to 3.3V logic levels. The device is packaged in a 7mm x 7mm, 48-pin TQFP and is fully specified over the -40 degrees Celsius to +105 degrees Celsius temperature range. Prices start at $5.25 (1000-up, FOB USA). Device data sheets, evaluation kits, and samples are available under NDA.
