Analog Analog Solutions—Robust, Reliable Performance CM0902 Dual High-Speed CAN Physical Layer Overview Industrial Applications The CM0902 devices with Dual high-speed CAN physical layer are Freescale’s standard •Transportation cost-effective products used to convert digital protocol information into analog CAN Heavy vehicles communication. They target CAN high-speed operation with two fully independent CAN Agriculture machinery interfaces in a 14-pin SOIC package. Aviation systems The CM0902 supports long-length CAN node interconnects for industrial applications and has an option with a built-in transceiver dominant timeout feature for automotive applications. Freescale’s robust CM0902 dual CAN high-speed physical layers offer extremely low quiescent current while exceeding the most stringent EMC/ESD requirements without added circuitry. Off-road recreational equipment Trains Electric Vehicles The CM0902 allows for the implementation of a cost-effective system. These parts minimize •Backplanes external circuitry and save system cost, including the elimination of common mode choke. •Lift/elevators It’s easy to get started with the KIT33CM0902EFEVB and KIT34CM0902EFEVB evaluation • Factory automation boards. These small evaluation boards can be used for quick application prototyping and demonstration of the CM0902 products for fast design and short time to market.
