Maxim Integrated Products has added the latest member of its high-speed LVDS serialiser family, the MAX9249 serialiser with LVDS system interface. The serialiser pairs with the MAX9260 deserialiser to form a gigabit multimedia chipset that provides a bi-directional digital-video link over a single DC-balanced twisted-pair or differential line. The company's proprietary, differential, full-duplex control channel eliminates the need for an external CAN or LIN interface, simplifying design while saving space and cost. This approach enables bi-directional communication with the display module, as well as programming of camera settings through a UART/I2C interface on a frame-by-frame basis. The MAX9249/MAX9260 chipset is suitable for automotive infotainment and camera applications such as navigation, sign recognition, collision avoidance, night vision, and lane departure. The chipset offers programmable spread-spectrum modulation to reduce EMI, making it easier to pass automotive compliance tests. This chipset allows isolation between the serialiser and deserialiser through AC-coupling, and provides hot-swap capability to increase fault tolerance.
