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…
Part Number: DP83822HF Dears:
when set to 100M, DP83822 will lose packet, but 10M is OK. Could you please help check what need to be done to solve this issue ? Processor is imx6ull.
below is the configuration.

Hi Team,
DP83822HF cannot be pinged using a PC (DP83822HF optical port, rewired to RJ45 connector via fiber optic transceiver, connected to computer side) .
Please see the following debugging steps:
1) 2 fiber transceivers are…
HI.
> 1) Disconnect DC blocking caps and NOT short across
It takes time and effort to prepare for the exam, so we ask that it be conducted separately.
> 2) With normal setup, toggle 0xA[14] and restart the PHY via 0x1F = 0x4000
If bit14 is 0, the…
Part Number: DP83822HF Do TI support schematics design review? We are using the mentioned Ethernet PHY chip and would like to get TI's expert opinion on design before we go into production.
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.
Twincat…
Part Number: DP83822HF Hi,
Good Day.
Pin TX_CLK mode output in the state during reset and RGMII mode : Customer's sequence:
- First: In reset mode (pin reset_n in low for a low during and the pin return in high), this pin "TX_CLK" is configurated in…
Hi Thomas,
Could you hold the reset button for a long time (around 5s) before you release it while you are power cycling the board to see rather that help with the link up issue? I want to see rather it is the power sequence issue.

Part Number: DP83822HF Hi Experts,
In RGMII mode, the pin RX data (x6) have to be 50 Ohm impedance.
In the datasheet, we did not find the paragraph that explains the presence of the internal impedance (50Ohm).
Question: Is there an existing internal…
