  • SN65HVD24: Transmission using long cable with surge absorption

    Part Number: SN65HVD24 Hi Used SN65HVD24, failing transmission of 300 meter cable at 4MHz rates. At this point, a surge absorption part is used for requirement of IEC61000-4-5. If absorption part is removed, transmission can be passed above…

  • SN65HVD23: Is there a device like this one that allows more nodes?

    Resolved
    Part Number: SN65HVD23 Other Parts Discussed in Thread: SN65HVD24 , THVD1520 , THVD1550 , THVD1420 I'm trying to find an RS485 half-duplex transceiver that can handle over 100 nodes at a distance of over 100 meters and a speed over 10 Mbps (20-30 Mbps…

  • RE: Cool RS-485: Receiver Equalization Boosts Bus length of High-speed Networks

    Awesome post, Figure 3 though doesn't really match the figure provided in SN65HVD24 datasheet. E.g. on Figure 3, for distance of 1000m, signaling rate is around 2Mbps. While in the datasheet, it shows below 1Mbps for 1000m. Thoughts? Also, if Figure…

    Resolved
    Hi Randy, The pre-emphasis function is generally used to help extend the range of a link. Can you please let us know the data rate and cable length/type for your application? We can then check if THVD1552 may be suitable. Also, although we do not have…

  • RE: TIDA-00790: Cable length and bit rate

    Resolved
    Hi Max Thank you for your reply. I had forgotten that full-duplex transceiver is required. SN65HVD24 can offer good performance, but it is half duplex device and it seems high class. Let me close this thread relevant to TIDA. Thank you for…

    Hi Raghu, I think your analysis is a very good starting point. (I say "starting point" here because it is difficult to arrive at an answer to this sort of issue without some kind of testing as well.) I think you may be overestimating the loss, though…
