Part Number: DP83822HF Hi,
We use DP83822HFRHBR IC in our design. We want to use PHY as RMII Master mode, but we want to do it without using bootstrap resistors. Could it be done without using these resistors?
Best regards.

Hi,
I am currently working with the DP83822HF PHY interfaced with an AM437x processor , and I am encountering an issue related to the PHY's mode configuration during power-up.
Due to inconsistent voltage levels…

Hi Team,
Posting on behalf of our customer.
According to section 7.6, “Timing Requirements, Power-Up Timing” , T2 is defined as a maximum of 200ms after power-up between reset and MDC. However, in section 7.8, “Timing Requirements…
Part Number: DP83822HF Hello TI Support Team, We are designing with the DP83822 in RMII master mode and would like to confirm the behavior of the RMII TX Clock Shift feature.
Context:
PHY mode: RMII master (PHY outputs the 50‑MHz reference clock to…
Part Number: DP83822HF Tool/software: Hi
I modified some registers during the test of DP83822HF registers. I thought the IC would reset after restarting, but the behavior of the IC changed after a certain test. RD_P, RD_M, TD_P, TD_M changed from unstable…
Part Number: DP83822HF Tool/software: Hello,
I am currently working on integrating the DP83822 PHY with an STM32H735IGT3 microcontroller to establish Ethernet connectivity. I have configured the Ethernet interface, and when I connect the Ethernet cable…
Part Number: DP83822HF Tool/software: We are currently in the process of integrating the DP83822HFRHBR (an extended temperature, robust 10/100-Mbps Ethernet PHY transceiver with fiber support and 16-kV ESD protection) with the STM32H735IGT3 MCU. However…
Part Number: DP83822HF Good morning!
In our schematic we substituted the PHY KSZ8081MNXIA with PHY DP83822HFRHBT.
Attached there is the complete scheme.
We have the following problems:
TXD0/TXD1/TXD2/TXD3 pins do not move, they are always LOW…
Part Number: DP83822HF Hi Team,
While Referring to DP83822 Trouble Shooting Guide , Under Section 2..4.2 Probe the RBIAS pin, it says following
Measure the DC value of the voltage across the RBIAS resistor and confirm that the voltage is 2.7 V
