TCAN1043HG-Q1：CAN related question

HongFan Zhao

Part Number: TCAN1043HG-Q1
Other Parts Discussed in Thread: TCAN1043,

Tool/software:

1.If the CAN controller uses the PLL to generate the operating clock frequency (either 40 MHz or 80 MHz), the long-term jitter of the PLL must be less than 2ns. Can the TCAN1043 chip meet this requirement?

2.Did the TCAN1043 chip pass the IOP testing provided by C&S group GmbH?

3.Does the TCAN1043 chip comply with version 2.0.0 of CIA601-4?

 

Thanks for your help.

    Hi HongFan,

    Thanks for reaching out on E2E!

    What specifically made you select the TCAN1043HG? If you do not need the 70V bus protection (denoted by the "H" suffix), then I highly recommend using TCAN1043N or TCAN1043A. These are on a newer process tech, and these devices support a higher data rate and have an improved cost structure, among other improvements. 

    1. In general, CAN transceivers do not specify jitter. This is because there are many variables that affect jitter such as cable length, node count, and bus characteristic impedance. However, TCAN1043 is fully compliant with the ISO 11898-2 standard which defines the CAN physical layer so I do not see any particular issues here. 

    2. Yes. Typically, you can reach out to your TI representative for all device tests and certifications. You are also welcome to email me at ethan.s@ti.com and I can send over this document.

    3. I believe you are referring to CAN SIC, where the latest version is defined in ISO 11898-2:2024. TCAN1043 is not a CAN SIC device. TCAN1473 is the SIC version of TCAN1043. However this device is currently in a preview stage: https://www.ti.com/product/TCAN1473-Q1 

    Let me know if that answers your questions,

    Hi,Ethan
    Your answer has very well addressed my question.
    But I have another question want to ask you.

    1.Does the TCAN1043HG-Q1 comply with ISO11898-1 standard？

    Hi Zhao,

    Glad that helped.

    ISO 11898-1 is the standard for the data link layer and physical coding sub-layer. This is intended to standardize the microcontroller, not the transceiver. TCAN1043 (which is a transceiver) is only standardized by ISO 11898-2. 

    Best,

    Ethan
