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 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
…
Part Number: DP83822HF Tool/software: Hello,
We are using DP83822HFRHBR with STM32H7 MUC in RMII mode, and we are not able to Detect the PHY using PHY ADDRESS.
We checked below for Verification,
1. 25MHz Clock input to PHY --> coming good.
2.…
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 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 detection…
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…
