Freescale Introduces High-Speed CAN Transceivers
November 25, 2013 by John Day
Electromagnetic compatibility (EMC) and electrostatic discharge (ESD) are critical requirements in harsh industrial and automotive environments due to the close proximity of a wide range of networked electronic systems and devices.
According to Freescale, its MC33901 and MC34901 chokeless CAN high-speed physical layer transceivers deliver outstanding EMC performance and high ESD robustness without the need for external components, thereby reducing overall system costs.
The devices also offer fail-safe features to assist with system functional safety, as well as exceptionally low quiescent current down to 8 micro amps.
The MC33901 and MC34901 products convert digital protocol information into analog CAN communication across in-vehicle networks, as well as long-length CAN node interconnect for industrial applications.
The Freescale CAN transceivers are suited for safety-critical industrial applications as well as for automotive body electronics, power train and infotainment systems. Both products offer outstanding performance at 2 Mbps baud rate to address CAN FD (flexible data) application requirements.
