DP83TC811S-Q1: DP83TC811EVM Diagnostic Toolkit

Part Number: DP83TC811S-Q1
Other Parts Discussed in Thread: DP83TC811EVM

Hi,

Few queries regarding the diagnostic function:

1. Temperature and Voltage monitor

a) What is the accuracy we are looking at for the temperature and voltage monitoring? Based on the design of the DP83TC811EVM board.

b) For the temperature, is there any recommended measurement method? If we are to based on thermo-couple on the surface of the PHY IC, is it ok?

2. SNR/SQI monitoring

a) Is there any typical performance graph of SNR/SQI vs. temperature and voltage fluctuation based on DP83TC811EVM?

b) There is a demo video on TI website showing the setup of injecting differential noise to the board. Is there any details on the noise requirement and setup?

Please help to advice. Thanks.
