Part Number: DP83TC814R-Q1 Hello Expert,
I'd like to know about the Boot strap latch-in timing when they after release RESET_N after VDD supplied. Their RESET_N release timing is as follows.
For the case of RESET_N and VDD supply becoming high simultaneously…

Hi,
Good Day. This component needs a default config and I want to know if all of the required config (Table 8-17) can be done via the MDIO (SMI) interface. Could you let me know how this is done?
Please advise. Thank you very…

I am Piyush Nahar, Hardware Design Engineer from Minda Instruments Ltd, Pune(India).
I have query about the MDC & MDIO pin mapping/interfacing with the host controller- do we need to connect these two pins to GPIO pins or…
Part Number: DP83TC814R-Q1 Hello expert,
My customer is designing circuit using DP83TC814R-Q1. Then, we have question regarding RX/TX pin under RMII mode.
For this pin, there isn't internal pull resistor under RMII mode operation. Then, they'd like…
Part Number: DP83TC814R-Q1 Hello Expert, My customer is considering to use DP83TC814R-Q1 under RMII mode. In this mode, TX/RX_D[3:2] and TX_CLK will be unused. Then, could we float this pins or should we need to set as PD or PU?
Thank you and best regards…
Hello Kazuki,
You are right regarding TX_*. It is better if we enable TX_* buffers from SoC side before we can release RESET_N of the PHY.
Kazuki Kuramochi said: Is following my understanding correct?
Hold the RESET_N low initially
Power-up "PHY" and…
