Part Number: DP83822H Team, could you help with a couple questions of mine?
We are interested in running the DP83822 PHY in a forced configuration (forced crossover, full duplex, 100Base-TX). While we understand the higher level implications of this,…
Part Number: DP83822H Hi.
I am trying to design with Transformerless (Single Cap) topology using DP83822HRHBT.
May I refer to the document "AN-1519 AN-1519 DP83848 PHYTER Transformerless Ethernet Operation"?
For AN-1519, DP83822HRHBT is not…
Hi Tim,
Tim Eickelberg said: The waveform on the picture I measeured at RD_P (yellow) and RD_M (turqouise). There was nothing plugged into the RJ45 connector, so this is an open measurement. This should be one FLP.
Can you try to change the magnetics on…
Part Number: DP83822H We're using a DP83822H in our design that's configured for MII. The XI pin is getting 25 MHz. The problem we have is that when setting for 10 Mbps operation, we are seeing 1.25 MHz at the RX_CLK and TX_CLK outputs (we should…
Part Number: DP83822H Hi,
We are using DP83822 Phy for IEEE1588 PTP in MII mode. In the data sheet mentioning only the RMII Master/slave operations.
Is there any strapping options needed for MII master/Slave operation for PTP.
Also when we are using…
Part Number: DP83822H Other Parts Discussed in Thread: TIDA-00299 Good mornig!
We are using the DP83822 phy with ET1100 in out ethetcat boards.
We are testing our boards with EFT pre-compliance tests. But at 2kV they lost the comunication with the ethercat…
Part Number: DP83822H I need to define the memory structures for the DP83822H. Type of memory (RAM, ROM, etc...), size, and function. I believe these functions have some memory, but feel free to correct me:
MII Interface
TX Block
RX Block
Control reg…

Reaching out about the use of this 1V8 supply voltage variant of the unit above the recommended operating condition [1.71V, 1.89V], but below the max input voltage. Seeing if there is an increase in false carrier or link drops expected…

Hi Team, We are using the ‘DP83822HRHBR’ Phy chip which is interfaced with MPC5777C controller. The Phy Link is not up. We tried setting the Phy to 100MBPS in Full Duplex Mode.
