Abstract
A transceiver for sending and receiving data from a controller area network (CAN) bus is disclosed. The transceiver includes a microcontroller port, a transmitter and a receiver, wherein the transceiver is configured to determine bit timings from a data frame received by the receiver. The transceiver is further configured to detect attempts to introduce a signal glitch in a predetermined portion of the data frame and upon detection of the signal glitch, the transceiver is configured to invalidate the data frame on a transmission line and/or disable the transmitter for a predetermined period.
