AMIS-30663 High Speed CAN Transceiver
Data Sheet
1.0 General Description
The AMIS-30663 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical bus and may be used in
both 12V and 24V systems. The digital interface level is powered from a 3.3V supply providing true I/O voltage levels for 3.3V CAN controllers.
The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. Due to the wide common-mode
voltage range of the receiver inputs, the AMIS-30663 is able to reach outstanding levels of electromagnetic susceptibility. Similarly, extremely low
electromagnetic emission is achieved by the excellent matching of the output signals.
2.0 Key Features
• Fully compatible with the "ISO 11898-2" standard
• Certified "Authentication on CAN Transceiver Conformance (d1.1)"
• High speed (up to 1Mbit/s)
• Ideally suited for 12V and 24V industrial and automotive applications
• Low electromagnetic mission (EME) common-mode-choke is no longer required
• Differential receiver with wide common-mode range (+/- 35V) for high electro magnetic susceptibility (EMS)
• No disturbance of the bus lines with an un-powered node
• Transmit data (TxD) dominant time-out function
• Thermal protection
• Bus pins protected against transients in an automotive environment
• Short circuit proof to supply voltage and ground
• Logic level inputs compatible with 3.3V devices
• ESD protection level for CAN bus up to ±8kV
