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 Hi TI , We are looking to do IEEE 1588 timestamping for our ptp protocol for digital substation applications . Current we are struck with the GEM of Zynq as it does not provide any time stamping support on its PHY. So we're looking…
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 Other Parts Discussed in Thread: TMDXRM46HDK , Hi team,
I had consulted the TMDXRM46HDK schematics. In the page 19, I have been seen that in the pins RX and TX of DP83640 there are resistences on serie but I can't find where they…
