Part Number: DP83822I Please provide some idea on PHY MAC Interace - Master / Slave Signalling to read / write operations? Also what are the different signals involved - how does MAC to PHY IO happens?
Part Number: DP83822I Please let me know boot up methodology for PHY DP83822I chip and how to ensure that any data I/O is done after the same. What are the coditions / registers to check a/ update nd how to ensure safe boot of DP83822I?
Part Number: DP83822I Dear Interface Team,
My customer is working on a XJTAG test for a design mounting the DP83822IRHBR.
For the development of the test, they need the BSDL model.
Is the BSDL model available for the DP83822IRHBR?
Thanks and best regards…

I am trying to understand how a PIN can be used for LED / GPIO1 interface. My understanding is that GPIO are used to access PHY registers? What is GPIO used for then - in Mode 2 we can control LEDs & GPIO both. If LED is bliking…
Part Number: DP83822I Hi!
I'm trying to add timing constraints on the FPGA side, which is receiving RX data from the DP83822I PHY.
I'm going for 100Mbps.
Figure 7-12 contains both SetupT and SetupR:
Why is both SetupT and SetupR…

Is there any standard, or recommendation on the clearance width between the below lines? For example, twice the width of the trace?
RMI and RMI
RMI and other signal line
RMI and GND
Other signal line (not RMI) and GND …
Part Number: DP83822I Hello,
My customer has an question for DP83822. The datasheet says that there are 2 classes, class B and class A, for line driver class like the below on P75.
What is the difference between them? Also could you tell me each merits…
Part Number: DP83822I We are replacing our PHY Chip to DP83822I in our networking embedded card. The same will be used for wired 100 Mbps RJ45 conection networking I/O and wish to know if there is any software emulator which is open source - likse using…
Part Number: DP83822I Hi,
Could you please let me know the datasheet updated item from rev E to rev F?
I found the rev F datasheet shows the above registers are updated.
Is it only updated in datasheet document (didn't change in silicon)? or was DP83822I…
