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…
Part Number: DP83822IF Hi,
We, at Teledyne, use the DP83822IF in our design. We purchased multiple DP83822 EVM boards. Our design and of course, the demo board work fine in 100BaseT which is what we use. We are now trying to convert our design to support…
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…
