Hi Pavlin,
These straps are correct to enable auto-negotiation advertisements for 10/100M, but please note they will also change the PHY address.
Although the default values of these straps will enable the same advertisements, adding pull ups is not an…
Part Number: DP83822I Tool/software: Hello,
I try to implement the DP83822I in a custom design.
The DP83822I is not responding:
<Pinging 169.254.85.90 with 32 bytes of data:> <Reply from 169.254.85.118: Destination host unreachable.>
I went trough…
Part Number: DP83822I Tool/software: Hi,
We use the DP83822I for the ethernet PHY, and We find the DP83822I has no singal output when the MAC is RGMII, and we force the MAC to RMII, the output singal is normal,
Please kindly to advise how to solve this…
Part Number: DP83822I Tool/software: Currently in our new design we are using DP83822IRHBR phy chip with IMX93 processor with RMII mode.
But REF_CLK output from IMX93 processor side, How to connect REF_CLK from processor to DP83822IRHBR PHY check. Could…
Part Number: DP83822I Tool/software: Is there wettable flank PKG for DP83822IRHBR?
If it has already supported, it would be helpful if you could also let me know.
Part Number: DP83822I Tool/software: Hello,
I am using Ethernet products (DP83822IHRBR) to operate EtherCAT.
Out of the two EtherCAT devices, one intermittently fails to establish an initial connection when repeatedly turned off and on.
(There are no…
Part Number: DP83822I Tool/software: Hello, I have a question for a strap configuration. In my customer case, the RX_ER of DP83822 is connected to AM335x's MII1_RX_ER pin which has an internal pull-down (51~210uA, 3.3V) They want to set the RX_ER strap…
Part Number: DP83822I Tool/software: We're having intermittent issue with the Ethernet XCVR. Applied 25 MHZ oscillator on pin 23. The PN of the Ethernet XCVR is DP83822IRHBT.
Pins 2 (TX_CLK), 23 (XI) and 25 (RX_CLK) probed with an oscilloscope. In…
Part Number: DP83822I Tool/software: hi,
A my account meets eye diagram test failure issue with DP83822I. Would you like kindly help give your suggestions? the schematic and layout file are attached.
we are now competing with YT8512 which was used by…
Hi Alvaro，
Yes，The current issue is resolved.Below are the test results of 10pcs board.
First, The Rx rate can reach 4.2MB/s，That's OK；
Second, Please pay attention to the Tx speed.The rate of Tx also increases a bit (about 7MB/s->8MB/s) when RCSR…
