Question about CAN Tranceiver SN65HVD2510D

Hi,

I have a question about CAN tranceiver product.

I'm searching CAN tranceiver for DeviceNet and found SN65HVD251D CAN Tranceiver.
Is it available to use SN65HVD251D for DeviceNet?

best regards,
g.f.

    Hi G.F.

    The DeviceNet standard is a higher-layer protocol that was developed by Allen Bradley that works on top of the CAN physical layer. While I do not have a copy of the standard since it is only available to DeviceNet members at http://www.odva.org/ I have seen the following list of requirements before. I went through the HVD251 datasheet and made a quick comparison for you.

    Parameter
    		 DeviceNet Specification HVD251
    Number of nodes 64 yes
    Minimum differential input resistance 20 kOhms 40kΩ
    Minimum differential input capacitance 24 pF 20pF Typ
    Bus pin voltage range (survivable) -25V to +18V ±36V
    Bus pin voltage range (operation) -5V to +10V -7V to +12V
    Differential output voltage 1.5V with 50 Ohm load 2V min @ 60Ω
    Maximum transmitter propagation delay 80 ns 150ns max for full transceiver loop delay (both parts added)
    Maximum receiver propagation delay 90 ns 150ns max for full transceiver loop delay (both parts added)
    Receiver hysteresis 150 mV (spec’d as typ) 100mV Typ
    Transmitter output current limiting internally limited
    		yes

     Please let me know if you have any questions.

    Thanks,

    John

    Hi John,

    Thank you so much for the reply.

    So, it seems that HVD251 matches DeviceNet Specification except propagation delay,
    and I understood as that HVD251 can be use for DeviceNet.

    By the way, I found from the HVD251 datasheet that DeviceNet was written as
    feature of HVD251. So, it's supporting DeviceNet.

    best regards,
