Daniel Wang
Part Number: DP83848Q-Q1 Tool/software: Hello team,
Can you please confirm if only a 50MHz (+/-50ppm) oscillator can be used for RMII?
Can we use 25M crystal for RMII?
Thanks!

Daniel
Part Number: DP83848Q-Q1 Tool/software: Is there any plans to add energy detect support to the upstream kernel driver for DP83848Q, or is there a reference implementation for a similar device?
Part Number: DP83848Q-Q1 Tool/software: Dear Team,
My customer is using the DP83848Q-Q1. CPU outputs the 50MHz clock to pin 28 (XI) of the DP83848Q-Q1 at present. RMII recognizes that data is synchronized by checking the riseof the clock, but if the…
Hi Wilson,
Wilson Yip said: Is there a spec that describes what that full FLP burst is sending and what data packet is supposed to look like?
The IEEE802.3 spec would describe the full structure of auto-negotiation. If you're concerned about the link…
Part Number: DP83848Q-Q1 Tool/software: Hello Team,
We have shortlisted DP83848Q-Q1 for our ECU design, since it supports 4 pair standard ethernet interface. We would like to know the EOL of the device, since we intend our ECU life to be 10-15 years…
