DP83TC811S-Q1: Question on Low Pass Filter
Part Number: DP83TC811S-Q1
My customer is evaluating DP83TC811S-Q1 and has some questions as follows,
Q1. Under power off, VDDA=VDDIO=0V of the DP83TC811S-Q1, if 100BASE-T1 signals are inputted into TRD_P/M of the DP83TC811S-Q1, are there any issues on the DP83TC811S-Q1?
Q2. Datasheet of the DP83TC811S-Q1, Timing Requirement on page 14, has ramp rate of VDDA and VDDIO at Power-Up Timing. VDDA and VDDIO ramp rate: Min=0.165 V/ms, Max=33 V/ms If the ramp rate was faster or slower than Min-to-Max range, what would happen on the DP83TC811S-Q1? Especially, if the ramp rate was faster than Min spec, what would happen on the DP83TC811S-Q1?
Q3. If the DP83TC811S-Q1 is Slave, is it possible to do the Compliance Test?
Q1: If the DP83TC811 is not being powered, then the PHY will not be on, therefore no signals could go through.
Q2: The timing requirements listed on page 14 are the specs for the part. You should expect to see the timing between these values.
Q3: Correct, you are still able to do compliance testing.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
