Hi,
It looks like the data is being sent to the PHY correctly, but when being transmitted it is being corrupted somehow.
Given that the PHY internal loopback test is successful, I think we should run compliance tests to make sure that the output of the…
Part Number: DP83848YB Tool/software: According to the datasheet, device Pin-20 and Pin-21 {RESERVED| within the HLQFP48 pin package each pin needs to pulled up through a 2.2K-ohm to 3.3V.
What happens to the device if the 2.2k-ohm pull-up resistor becomes…
Part Number: DP83848YB Hello, we use DP83848YB part on our equipment. On few cases (4 up to now), the equipment came back from our customer and not pinging any more at 100Mb/s, but pinging correctly at 10Mb/s (full duplex in both cases). When looking more…
Part Number: DP83848YB Hi Team,
Our customer wants to design a new board with 10/100BT. Since we have stocks of DP83848YB, he choose this device.However, the magnetics suggested in the application note are not available and some are already obsolete…
Hi Devitt,
Can you please get hold of EVM on ti.com and do the same compliance? This will give us an indication if there is any setup issue which is causing the failure. The EVM design is tested for compliance and we can use this as golden device.
DP83848I…
Part Number: DP83848YB Hello Team,
My customer needs confirmation about the device DP83848YB 100BT mode.
Since 100BASE-TX isn't dependent on link polarity. The IEEE 802.3 standard doesn't specify that 100BASE-TX should not rely on link polarity and use…
Part Number: DP83848YB Hi Team,
We have a customer requesting for the following information for DP83848YB. I have checked the datasheet but I can't find the specific answers to these questions. Can you please provide these information?
1) Is the memory…
Part Number: DP83848YB Dear Sir/Ms.
My customer designed DP83848YB Ethernet phyter, Because the TEST MODE of the MCU is not available at the time of the test. I want to reserve a probe point, and after SMT, I can test to confirm whether the DP8348 CHIP…
Part Number: DP83848YB Hi, Good day. I hope you are doing fine. Our customer is designing using the DP83848YB however they have question regarding the 68-Ω impedance stated on the datasheet (7.2.2.1). They want to know if it is necessary to have 68ohms?…
