Part Number: DP83640 Tool/software: Hi Team,
If customer's architecture is as shown below, can customer use the DP83640 to implement and support PTP? SOC (Support PTP) --SGMII--> DP83640 --PHY--> Connector --PHY--> DP83640 --RMII--> SOC (No Support…
Part Number: DP83640 Other Parts Discussed in Thread: DP83869 Tool/software: Hello,
We are currently using the DP83640 Ethernet PHY in our design, and it is configured in fiber mode (100BASE-FX) using the FX_EN_Z pin .
This setup works as expected…
Part Number: DP83640 Tool/software: We are facing two issue about using dp83640:Frequently, there is a "timed out while polling for tx timestamp" issue. It is suggested that "increasing tx_timestamp.timeout may correct this issue," but it is likely caused…
Part Number: DP83640 Tool/software: Hi,
Could someone check my DP83640 schematic in RMII mode? I would like to use with ptp sync mode. Mcu will use stm32h723. ETH_CLK = 25MHz from mcu.
Thank you.

Part Number: DP83640 Tool/software: We have two questions regarding DP83640:
1. We would like to power the DP83640 from two different sources, powering IO_VDD w/a 3.3V (or 2.5V) of the microcontroller and powering the ANA33VDD PHY section from the generic…
Part Number: DP83640 we use dp83640 for ptp, most of time it works well.
but sometimes the clock change to abnormal random value. I use PTPClockRead to get the phy clock(sec. nanosec.).
Part Number: DP83640 Tool/software: Hi,
We are using the DP83640 and we need clarification on the temperature parameter in the data sheet.
Section 4.3 "Recommended Operating Conditions" specifies Industrial Temperature Ti as -40C to 85C.
Is this…
Part Number: DP83640 Tool/software: Dear TI,
is it possible to use JTAG for diagnosing the state of the PHY in application? This would be very valuable in one of my projects.
Could you provide any documentation or guide for that, please?
Best regards…
