Part Number: DP83822IF hi.
Strap set up for DP83822IF fiber drive
After testing, the pull-down straps of RX_D0 and RX_D1 did not work properly
If the pull-down strap of RX_D0, RX_D1 is applied with RH 2.49K pull-up resistance, it is set datasheet mode…

Part Number: DP83822IF Other Parts Discussed in Thread: AM2634 , Hi,
I am trying to use the DP83822IF PHY for a board using AM2634.
Can you give me some registers for using the DP83822IF?
Also, I don't understand it well, the DP83822IF register can be…
I have a few suggestions to help isolate where the signal chain may be failing.
To validate MAC side:
- Enable MII loopback on DP83822 (0x0[14] = '1')
- Sending packets from LAN9252 or upstream host, verify these packets are looped back over DP83822…
Part Number: DP83822IF Hi team,
The manual for DP83822IF mentions the equal length requirements for layout:
What are the specific length requirements for SMI communication and RMII communication? How much can't the difference be? please reply as…
Part Number: DP83822IF Dear Ti Community,
We are currently in the process of designing a system that will utilize the DP83822IF for a fiber application. Given the constraints of our power supply, we are keenly interested in understanding the power consumption…

Hello,
I generated a custom PHY driver source for the DP83822IF.
MCU is AM2634
First of all, I changed the ETHPHY from Sysconfig to Custom and completed Device Name settings and…
Part Number: DP83822IF
Hello,
I need to set LED_0 of DP83822IF to MII_LINK
and i need to set COL to operate as LINK_OK
When I looked at the datasheet, I understand that LED0 and COL pins are set in the MLEDCR register.
However, if I look at page 52…
