Part Number: DP83848I There are issues with impedance matching in the current use of chips. Of course, when used in conjunction with the network transformer HR641201E (brand: HANRUN) and an RJ45 port without isolation, how should the impedance matching…
Hi Fabio,
I had a look at the schematic and layout and did not find anything glaring. To help isolate the issue can you help to conduct the following experiments:
1. With MII isolate enabled ( register 0x0 bit[10] = 1). This will tell if the MII traces…
Part Number: DP83848I Hi team
My customer CVT wants to use our PHY device DP83848I in their commercial display project. The device is to support the microphone signal transmission with AES67 standard.
To ensure the audio quality, the PHY CLK_OUT Pin must…
Part Number: DP83848I Hi Experts,
This is Skylar responsible for GREE. GREE uses DP83848I and here are some questions. 1. Do we have MAC address in DP83848I? 2. how can we use DP83848I to get the 6 bytes MAC address? Look forward to see your reply!…
Part Number: DP83848I Hi
I'm designing an Ethernet circuit using the DP83848I and found your app note SNLA290. I have two questions about the statement "Maximum equivalent series resistance: ≤ 50Ohm" in the SNLA290 summary. [1] What is…
Part Number: DP83848I Hi all,
i am making dp83848vii interface with lpc54so18 and i changed phy and i am getting link status and autonogation but ping is not getting and i read all the register values are below (using lwipstack)
please help me to solve…
Part Number: DP83848I - What is the link partner?
The customer has an additional network cable adapter cable,
- What level is it failing at, and what level are you trying to achieve?
EFT and surges are both level 4, 4KV, the highest standard。
- When the PHY does lose link, wha…
Part Number: DP83848I Hi Team,
I would like to know how to set up continuous "0" data output.
Which registers must be set?
I found the continuous "1" data output setting in the CDCTRL1 register bit0:1 = '11' in the datasheet.…
Part Number: DP83848I The customer is using the network chip DP83848IVVX and is experiencing problems. When the EFT burst test is applied, the network port indicator will be off and the network connection will be disconnected. This should be a hardware…
Part Number: DP83848IDP83848I can become a problem if it receives a large number of packets in an instant (network storm), as described below
PHY link & Act lights off.It also reboots because the device receives excessive packets during a network storm…
