Datasheet

Maxim introduced the latest member of its high-speed LVDS serializer/deserializer (SerDes) family: the MAX9259/MAX9260 SerDes chipset. This gigabit multimedia chipset 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 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/MAX9260 chipset is ideal for automotive applications such as sign recognition, collision avoidance, night vision, and lane departure.

Additionally, the MAX9259/MAX9260 offer programmable spread-spectrum modulation to reduce EMI, making it easier to pass automotive compliance tests. This chipset allows isolation between the serializer and deserializer through AC-coupling; provides hot-swap capability to increase fault tolerance; and allows on-the-fly frequency programming. Line fault detection and integrated self-test features check for link integrity at system power-up.

The MAX9259 operates from a 1.8V core supply, and the MAX9260 operates from a 3.3V supply. Both devices feature a separate input supply for interfacing to 1.8V to 3.3V logic levels. The MAX9259/MAX9260 are packaged in a 10mm x 10mm, 64-pin TQFP and are fully specified over the -40 degrees Celsius to +105 degrees Celsius temperature range. Prices start at $4.95 (1000-up, FOB USA). Device data sheets, evaluation kits, and samples are available under NDA.
