Other Parts Discussed in Thread: DP83640 Greetings !
We are integrating the DP83640 Ethernet Phy with STM32F769. Here we are facing issue while adding DP83640 in kernel dts file . Requesting you to kindly suggest us the syntax/configurations for dts file…
Part Number: DP83640 The datasheet for the DP83640 mentions the CLK_OUT pin can be configured to pass-through the 50MHz clock from X1.
Please see the image attached.
This is shown as source 4 in the image.
However I can not figure out how this is configured…
Part Number: DP83640 Hi team,
One of our customer's issues, I'm forwarding it below, could you please provide some troubleshooting suggestions? Any troubleshooting ideas are appreciated.
Currently we are using the DP83640PHY chip to implement the…
Part Number: DP83640 Other Parts Discussed in Thread: DP83630 Team,
From you experience is it possible to design a PCB for both package? (in order to solder the one IC you can source at this point of time) DP83640: 48-pin LQFP Package (7 mm × 7 mm)…
Part Number: DP83640 Hello,
We have our device setup to use RMII. We have both RX_DV and TXD_3 strapped HIGH. However, the resistors were improperly spec'd to 10K. We are seeing on occasion that the system boots without ethernet working and suspect that…
Part Number: DP83640 Hi,
I'm trying to send Layer 2 ptp pdelay request or sync messages (any event message) to DP83640. I can see content of received message is correct. But when I control RXTS_RDY bit of PTP_STS register, I see that it is not set.…

Hi team,
Does DP83640 can receive external clock data package and then analyze it for local system use? thanks.
Best regards,
Yang
Hi,
I am not sure what to recommend next. Could you please post a scope capture of the tx clock line between the MAC and the PHY?
Also please remove the cable and use ethtool to verify the link goes down and then plug in the cable and verify the link…
Part Number: DP83640 Other Parts Discussed in Thread: ALP Hello,
We plan to validate accuracy of PTP synchronization on DP83640 using SNLA098A setup.
Are exsisting DP83640T-EVKs suitable for this evaluation?
And how can we find "ALP FPGA bord" now? Is…
Part Number: DP83640 Dear Engineer:
I am working on a project to achieve PTP1588 clock synchronization using MCU+DP83640. I have drawn the first version of PCB board, and its schematic diagram is shown in the picture. Now, I have encountered some problems…
