Using the Analog LaunchPAD application and DP83640T-EVK (Ethernet phy with USB access). Select the tab Cable and Jitter (Variance) and Receiver SNR values are reported with a rating Excellent, Fair, Poor etc. What is the range for each rating? ie Jitter range some number is Excellent, Jitter range is Fair and also for the Receiver SNR etc. The reason for asking, I've got a Web Interface accessing the same numbers in our HW design and need to know the each of the ranges, so the user sees the same indication of what is Good, Fair and Excellent. There is a source for this application? I saw the SDK, but did not see how to decode the values into some ranges, ie Excelleent, Fait, Poor.
I could not find anything in the Data sheet to help determine what are acceptable ranges for these values (Jitter.Variance) and Receiver SNR.
