ISO3086T: Noise test data for low data rate

Satoshi
Guru 19685 points

Part Number: ISO3086T

Is there noise(EMI) test data on the low data rate for ISO3086T?

※Less than 500kbps, it is customer spec. 

Customer is concerned that ISO3086T's noise specification, because this device is very high speed.

And, I feel that ISO308x series is in charge of high speed application.

If there development background, please let me know.

Best regards,

Satoshi

    Hi Satoshi,

    Please find attached emissions plot below. This measurement was done according to the CISPR22 standard.

    The plot shown below is that of a device similar to ISO3086T, we expect the emissions to be the same for this data rate.

    Thank you for reply.
    Sorry, please let me know about emission plot below.
    ・Please let me know about mean of upper side line.
    (Line for changing right angle)
    ・This picture's character and number is crushed.
    Is there clean (or large) plot data?

    Best regards,
    Satoshi

    Satoshi-san,

    The radiated emissions has been done according to the CISPR22 standard. The upper side line is the Class-B limit line for CISPR22 standard. The limit changes from 30dB to 37dB at 230MHz frequency. As you can see we have >15dB margin with from the Class-B limit, which is very close to the noise floor.

    Apologies for the image being of poor quality. It reduced in quality when I attached with E2E post. Please find attached word document with image inside.
