TCAN1042-Q1: About shipping test

Junya Kato

Part Number: TCAN1042-Q1

Hello Team,

Are the following inspections done in the shipping test?
- Voltage of CANH/CANL (@ high speed such as 2Mbps,5Mbps)
- Speed of CANH/CANL (@ high speed such as 2Mbps,5Mbps)

If so, is it possible to tell me what kind of examination method is?
My customers want to do that test, but it is hard because of high speed.

Best regards,
Kato

    Kato,

    Do you mean are these parameters checked before we ship devices to customers? The devices in our group are tested against specification parameters
    in the datasheet to verify their values fall within a given range. 


    Can you elaborate on what exactly the customers want to test? It seems like they want to check the dominant and recessive voltage levels at 2Mbps and 5Mbps, and want to check the quality of the waveform at 2Mbps and 5Mbps as well. Is my understanding correct?

    Regards,

    Kato-san,

    I wanted to check in with you, did you have a chance to know what the customers want to test?

    Hello Eric-san,

    Sorry for my late reply.

    Can you elaborate on what exactly the customers want to test? It seems like they want to check the dominant and recessive voltage levels at 2Mbps and 5Mbps, and want to check the quality of the waveform at 2Mbps and 5Mbps as well. Is my understanding correct?

    Your above recognition is correct.
    My customers wanted to check the voltage level at high speed communication and check the quality of the waveform.


    Do you mean are these parameters checked before we ship devices to customers? The devices in our group are tested against specification parameters in the datasheet to verify their values fall within a given range.

    In my customer's environment, it is difficult to check the quality of the high-speed waveform, so I informed my customers of the above.

    Best regards,
    Kato
