Alvaro (Al-vuh-roe) Reyes said: Earlier you mentioned a ripple of 3.1v-3.6V. The VDDIO Screenshot you shared doesn't show this, please clarify as it is important to the debug.
Did you try replacing the ferrite bead with a 0 Ohm resistor?
Nope it is…
1) PHY is unable to do JTAG boundary scan operations if the nRESET (pin 43) is held low. 2) There are no initialization steps to set in boundary scan mode, So the device respond in the chain if the bootstrap configuration is not…
Part Number: DP83869HM We want to use the DP83869HM PHY in our design, but for backward compatibility the system must support RGMII to Fiber in TX-only mode.
Is this possible with this device? Do I need to manipulate the SD signal?
I want to reiterate again on the problem I see in the application.
Transfer of data from PC to DP83826 will not be a problem as the PC transmits data in Ethernet format.
Transfer of data from DP83826 is a problem as the data from your long…
Part Number: DP83869HM Hello, My customer is considering DP83869HM for their new design and would like to confirm if DP83869HM can meet their requirements listed below. Does DP83869HM can support all their requirements? - Number of ports = 1 or 2. …
Part Number: DP83869HM Other Parts Discussed in Thread: DP83869 Hello Team,
we are using DP83869 in our design with following operating modes:
(a) Media Conversion Between Copper and Fiber
(b) PHY RGMII to BASE100-Fx Fiber Ethernet PMD connections (SFF…

Does we have a automotive-grade DP83869HM plan ?
My customer need a automotive-grade RGMII-SGMII bridge IC.
AEC-Q100 grade2 -40~105C
Operation temperature =85
I am very sorry for the delay in response.
I checked the design and looks like SGMII Auto-neg done is available in both 0x37 and 0xC01. However, in SGMII-Cu mode, link status in 0xC01 is always connected to 0. We will have to rely on SGMII Auto…
