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…
Hi Rajesh!
Thank you for clearly providing the register log in a table, this makes it much easier for me to review. Please find my responses below.

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 Tool/software: For DP83822, there is a guidance where AVD and VDDIO must not exceed 0.3V prior to complete supply ramp, with an additional footnote suggesting AVD to ramp up after VDDIO to avoid false detection of VDDIO. False…
Hi Hitesh,
Thank you for the observation.
Are you writing any register during the bootup?
Does reset PHY solution not work for customer? If customer writing register 0x001F to 4000 or register 0x001F to 8000. Does that help with with the application…
Part Number: DP83822HF Hi Ethernet Team,
Is there any timing requirements for signal detect for our PHYs, in particular the DP83822HF? My customer recently found that they might have an earlier assertion of this signal from their transceiver and wants…
Part Number: DP83822HF Other Parts Discussed in Thread: DP83822EVM Hi experts,
Customer is using DP83822HF in 100BASE-FX mode, however due to some reason the signal detection feature is disabled through pin strap of RX_ER (configured in MODE 1). Now customer…
