Part Number: DP83822HF Hi,
Pin TX_CLK mode output in the state during reset and RGMII mode : Customer's sequence:
- First: In reset mode (pin reset_n in low for a low during and the pin return in high), this pin "TX_CLK" is configurated in…
Hi Gerome, Sorry for such a late response - I have been out of the office due to being ill the last few days.
Let me try to explain things a little bit better. Currently we are creating a custom board in which we are interfacing a TMS570LC4357 with a DP83822HF…
Part Number: DP83822HF Good morning!
In our schematic we substituted the PHY KSZ8081MNXIA with PHY DP83822HFRHBT.
Attached there is the complete scheme.
We have the following problems:
TXD0/TXD1/TXD2/TXD3 pins do not move, they are always LOW.
Part Number: DP83822HF Hi Experts,
In RGMII mode, the pin RX data (x6) have to be 50 Ohm impedance.
In the datasheet, we did not find the paragraph that explains the presence of the internal impedance (50Ohm).
Question: Is there an existing internal…
Part Number: DP83822H Other Parts Discussed in Thread: TIDA-00299 Good mornig!
We are using the DP83822 phy with ET1100 in out ethetcat boards.
We are testing our boards with EFT pre-compliance tests. But at 2kV they lost the comunication with the ethercat…
Part Number: DP83822HF Other Parts Discussed in Thread: AM4376 Hi
This is with reference to a custom Ethernet board that we have developed using DP83822HFRHBT and AM4376 processor.
We have utilized 2 PHY IC's in above design and interfaced same…
Part Number: DP83822HF Hello,
I am new to ethernet and PHY. So please excuse wrong questions.
I am trying to interface the above part with Zynq 7000. PFA schematic for further reference. I am trying to configure the ethernet in RGMII mode but the ethernet…
Part Number: DP83822HF hi, team we are using DP83822HF PHY device, and meet some problems, so we need your help. (1) the interface between MAC and PHY is MII default. (2) we want try some stress test. for one transfer, data is send from MAC to PHY via MII…
