Part Number: TCAN1044V-Q1

Hi team,

Could you kindly help provide corresponding spec of Tbit(TXD)=2000ns? Thanks!

    Hi Jiawei,

    The bit timing parameters for this device are based off of the requirements listed in the ISO 11898-2 CAN specification. There is not actually a large expected difference in bit timing based on the data rate that is being used apart from the small impact that bus settling time has on this behavior (less impactful at slower data rates). 

    In this case I would expect that the Tbit(RXD) deviation at 2000ns bit times to match that of the 500ns specification in the datasheet, meaning that the expected recessive bit would deviate by -100ns to +50ns. This would result in a Tbit(RXD) between 1900ns and 2050ns. 

    Let me know if this information is sufficient for the customer's needs and if you have any more questions. 

    Regards, 
    Eric Schott
