I followed the link you provided. It does note that the DP83640 is used for IEEE 1588 PTP support, but I did not find any mention of issues with One-Step mode. If you could provide more detailed information, I will look into this.
Independent of the Renesas…
Hi Ross san, We have some additional questions. So, could you let know us followings? <Question1> Why is "CENTER TAP IS PULLED TO VDD" required? -It means TP-: GND, TD+ :+6.6V. -Wtih CENTER TAP conneting to +3.3V, it is possible to remain equilibrium…
