LVDS Serializer Eliminates CAN/LIN Interfaces

Exploiting a proprietary full-duplex control scheme that eliminates the need for a separate CAN or LIN interface in automotive infotainment and camera applications, the MAX9249 serializer with LVDS system interface pairs with the MAX9260 deserializer to form a Gigabit multimedia chipset that provides a complete bidirectional digital-video link over a single dc-balanced twisted-pair or differential line. 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 chipset offers programmable spread-spectrum modulation to reduce EMI, allows isolation between the serializer/deserializer through ac-coupling, provides hot-swap capability to increase fault tolerance, and provides on-the-fly frequency programming. Line fault detection and integrated self-test features check for link integrity at system power-up. The MAX9249 operates from a 1.8V core supply and features a separate input supply for interfacing to 1.8V to 3.3V logic levels. Available in a 48-pin TQFP measuring 7 mm x 7 mm with an operating temperature range from -40°C to +105°C, price starts at $5.25 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
