TCAN1145-Q1: Bit timing for 500kbps

Hi Team,

Could you help share the bit width spec for 500Kbps?

D/S only show 2Mbps(above 1 Mbps up to 2 Mbps) and 5Mbps(above 2 Mbps up to 5 Mbps).

    Hi Adrian,

    Per ISO 11898-2:2016 the limits for those timing parameters are not defined for intended use with bit rates up to 1 Mbit/s. So we don’t have those specifications. 

    While I don’t have any reference data, I would expect that the deviation at 500khz bit times to match that of the 2Mbps specification in the datasheet, this would result in a tbit(RXD) between 1640ns (-18%) and 2160ns (+8%), tbit(bus) between 1800ns (-10%) and 2100ns (+5%).

    Regards,

    Sean
