XL1040

High speed CAN transceiver XL1040 SOP8 FEATURES GENERAL DESCRIPTION • High speed (up to 1 MBaud) The XL1040 is the interface between the Controller Area Network (CAN) protocol controller and the physical bus. It is primarily intended for high speed applications, up to 1 MBaud, in passenger cars. The device provides differential transmit capability to the bus and differential receive capability to the CAN controller. • Very low-current standby mode with remote wake-up capability via the bus • Very low ElectroMagnetic Emission (EME) • Differential receiver with high common-mode range for ElectroMagnetic Immunity (EMI) The XL1040 is the next step up from the 1050 high speed CAN transceiver. Being pin compatible and offering the same excellent EMC performance, the XL1040 also features: • Transceiver in unpowered state disengages from the bus (zero load) • Input levels compatible with 3.3 V and 5 V devices • Voltage source for stabilizing the recessive bus level if split termination is used (further improvement of EME) • An ideal passive behaviour when supply voltage is off • A very low-current standby mode with remote wake-up capability via the bus. • At least 110 nodes can be connected • Transmit Data (TXD) dominant time-out function This makes the XL1040 an excellent choice in nodes which can be in power-down or standby mode in partially powered networks. • Bus pins protected against transients in automotive environments • Bus pins and pin SPLIT short-circuit proof to battery and ground • Thermally protected.
