Part Number: DS15BA101 Other Parts Discussed in Thread: DP83869HM , , SN65LVDS100 Hello There,
we use DP83869HM as PHY for 100M media converter. In order to connect Optical receiver we need to meet PHY input specification of 0.3-2.0 V for differential…
Hi Timber,
From the data you sent, it appears that the PHY is either not fully functional or not fully configured. To debug, it would require checking the health of the device. Our troubleshooting guide and schematic checklist would have good starting…
Part Number: DP83869HM Other Parts Discussed in Thread: DP83869 Hello,
We have a set up with a custom PCBA and a backpanel, both containing an DP83869HM PHY chip. See this block diagram: ┌──────────────────────────────────────────┐ ┌──────────────…
Part Number: DP83869HM Other Parts Discussed in Thread: AM5748 Hello,
DP83869HM is interface to AM5748 through RGMII0 interface. Communication is established but link is not up. Since we are using RGMII to Copper mode, the GTX_CLK must be 125MHz but we…
Part Number: DP83869HM Other Parts Discussed in Thread: USB-2-MDIO Hello,
I'm currently running ethernet compliance testing and am trying to generate an all-ones pattern for 10Base-T via register 0x25 in the DP83869HM but can't seem to get anything to…
Part Number: DP83869HM We use three DP83869HM (SGMII to copper) on a Intel Elkhart Lake CPU.
The PHY connected to the PCH always works but the other two connected to the PSE seem to have problems at establishing the SGMII link sometimes. Bit 8 in the SERDES_SYNC_STS…
Part Number: DP83869HM Other Parts Discussed in Thread: DP83869 Hi
According to dp83869hm datasheet, in 9.4.2.1:
In fiber mode, the speed is not decided through auto-negotiation. Both sides of the link must be configured to the same operating speed.

Hello there,
We would like to ask for help to debug the DP83869HM used as 100M media convertor.
For communication link we use two units of DP83869HM in 100M Media…
Part Number: DP83869HM Hi team,
Accodring to the datasheet below, default is set to 50 Ω by trim before shipping the device from TI, but the default register value of MAC_IMPEDANCE_CTRL can vary by process. Does this mean the register value of MAC_IMPEDANCE_CTRL…
