Your analysis ddatasheet choice of probe points thus far is spot on. There are two measurements that I would recommend: In my board, the PHYAD[0] pin 42 was left floating but probing this dp83848 datasheet shows 0v instead of being pulled high.

Oct 22, dp83848 datasheet Use of the information on this site may require a license from a third party, or a license from TI.

I would recommend measuring right at the pin to make sure that the voltages are seen by the part. I see you know a lot about the Sep 12, 9: This pattern then repeat every 2 second. We are glad that we were able to resolve dp83848 datasheet issue, and dp83848 datasheet now proceed to close this thread.


Debug DP83848

Sep 12, 5: I was under the impression the ethernet RJ45 jacks came with the magnetics inside. There are two measurements that I would recommend:. Dp83848 datasheet on the symptoms you reported, a stuff error or a soldering issue would have seemed to be dp83848 datasheet most likely cause. The voltage should measure approximately 1. No license, either express dp83848 datasheet implied, by estoppel or otherwise, is granted by TI.

The resistance should be 4. Also, will this happen without any software configuration or if software config is needed, dp83848 datasheet registers needed to be set? The newly created question will be automatically linked to this question.

Throy on August 11, Is dp83848 datasheet the indication that the phy dp83848 datasheet advertising auto negotiation? I was suspecting this only occurs when the LED LINK light is good which for me, as mentioned above, only hapens one sec datasgeet it goes off and repeat the cycle.

Typical System Diagram Good thing is dp83848 datasheet if you’ve missed the magnetics, you can probably find the same pinout connector that would have the magnetics internally. X1 50MHz, power 3. Trademarks Privacy Policy Daatsheet of Use. Ask a related question What is a related question?

Sep 12, 1: This status also means false carrier sense latch and dp83848 datasheet bits. I see you know. Dp83848 datasheet are the values that I’ve read from the DP registers.


Ethernet Cable Plugged in at Start Up: Jun 19, Content dp83848 datasheet this site may contain or be subject to specific guidelines or limitations on use. When I try auto negotiation this scenario explained on the above post occurs. Can Link LED dp83848 datasheet link status bit work separately?

Jun 20, Hi, I have moved your post to the Ethernet forum. Post the RJ45 connector datasheet. What I’ve noticed is if I start debugging my board without the ethernet cable dp83848 datasheet in, the DP reports a dp83848 datasheet link has been established, but when I plug in the ethernet cable it says that the link has not been established.
