Hi Michael,
From my understanding, both case 1 and case 2 are the same thing. By setting the device to RMII slave mode, the device will be configured to receive a 50MHz clock reference instead of a 25MHz one. Essentially, you are trying to set the device…
Part Number: DP83826EVM Other Parts Discussed in Thread: USB-2-MDIO Dear team, Hi, I want to conduct MDI compliance test based on 100Mbps using USB-2-MDIO. If you look at the Register Description, in the case of 10BASE TEST, it is stated that the register…
Part Number: DP83826E Other Parts Discussed in Thread: , DP83826-EVM-AM2 Tool/software:
Hello.
I have some questions regarding the DP83826E.
Looking at the circuit of the DP83826-EVM-AM2, I see that the LED are driven by a MOSFET, whereas in another…
Part Number: DP83826I Other Parts Discussed in Thread: DP83826EVM Tool/software: Hi E2E Support,
I have a question about the capacitors that connect from the center taps of the Ethernet magnetics transformers to ground. I plan to use one DP83826I PHY…
Hi Yehuda,
Is there any case of DP83826 linking up in 100M? If you have DP83826EVM on-hand, can you try link and throughput test in 100M while linked to your custom board or the 100/1000M router?
The possible causes appear to be incompatibility with the…
Hi Brian,
I understand the confusion your are having. As a general rule of thumb trust the data sheet, they are usually the most up-to-date document you can refer to for our devices. The DP83826EVM was designed prior to the release of the DP83826, since…
Part Number: DP83848I Other Parts Discussed in Thread: DP83826EVM Hello.
I have a question about the DP83848 Auto-Negotiation feature.
I've configured the circuit as shown in the attached picture, and I'm wondering if it is set up correctly for 10BASE…
Hi Michael!
So I went into lab to check PRBS functionality on our DP83826EVM , here's what I found.
For PRBS packets to be sent, valid link must be up first.
By writing Reg 0x0 = 2100, you are disabling Auto-Neg and forcing 100 Mbps
Valid link will…
Hi Matt,
I am not sure if I understand your question completely. Are you struggling on the implementation of the LED for DP83826EVM? If so here is the explanation is the following:
Since all the strap we have for LEDs in DP83826EVM are pull down. Therefore…
