THVD8010: Are THVD8000 and THVD8010 interchangeable?

Part Number: THVD8010
Other Parts Discussed in Thread: THVD8000

Hello,

Providing the RFset and Fo is fixed to be 300kHz and below, they should be interchangeable. However, there is a table in THVD8010 datasheet and a graph in THVD8000 datasheet for Fo relative to RFset and I am unsure if they match. Do they?

Best regards,

    Hi Sebastian,

    1. Both the THVD8000 and THVD8010 have the same setting resistors for modulation frequencies between 125KHz to 300KHz

    2. They aren't  100% interchangeable because of the receiver threshold values - the THVD8010 can't reach as high of modulation frequencies as the THVD8000 but the THVD8010 has a much larger receiver hysteresis.

    THVD8000:

    THVD8010:

    So depending on the direct system these devices are placed in the THVD8010 is more noise resistant due to its higher required threshold - but that also means the THVD8010 will be more sensitive to attenuation than the THVD8000.

    Please let me know if you have any other questions and I will see what I can do!

    Best,

    Thanks, that is all I needed to know, we will revert to THVD8010 due to the lower cost. We don't need the higher bitrate the THVD8000 provides and will select an F0 that suits both.
