Hi all, I have some questions about Reset function as follows;
Q1.While the H/W or S/W Reset is ON, I think the LED output will be OFF. For example, when RESET is executed, what is the delay time from the output low state to the…
Part Number: DP83848K Would you let me know the range of resistance values for the weak internal pull-down of PHYAD1 to PHYAD4?
If there is no nominal value, calculate the resistance value of the weak internal pull-down using the following concept, Is…
Part Number: DP83848K Hello,
We are working on a commercial product in which uses ethernet phy DP83848KSQ from Texas Instruments.
It is interfacing with the internal MAC of MCU over RMII mode for 100Mbps.
We are looking to verify post power-up stabilization…
Part Number: DP83848K Hi team,
Here's an issue from the customer may need your help:
The customer use the GD32F450 with DP83848K to design the network portion. With RMII mode, the MCU provides a 50MHz clock, the MCU can communicate with the 83848…
