Other Parts Discussed in Thread: DP83865 is there information of resister address: 0x1C0?
For example, datasheet page 49 written in 0x1C0.1 (3.20 10BASE-T Half Duplex Loopback),
but I didn't find detailed information of these resister address.
Best…
Other Parts Discussed in Thread: DP83865 HI,
First Iam new to Ethernet phy world, my question might be basic for you. Iam trying to reset the DP83865 by writing 1 to bit 15 in the BMCR and wait until that bit clears it self. When done the BMSR bit 2 reads…

Other Parts Discussed in Thread: DP83865 Hello-
We are using the DP83865 in a new design and 10% or the prototypes can not establish a link at 1 Gbps. Some of them that can establish a link experience CRC errors. We need your help in debugging the problem…
Hi Team,
Please allow me to confirm the device operation about MDIO initialization.
The device requires 32 consecutive MDC clock cycles for MDIO initialization. Could the device start normal operation when there is only 31 consecutive clock cycles…
Other Parts Discussed in Thread: DP83865 Hello Team,
We are using DP83865 on our board and having trouble that the device would not link up when MDC is applied before PHY link up. If MDC is applied after PHY link up it it seems to be operating correctly…
Other Parts Discussed in Thread: DP83865 We have a design that uses the DP83865 and when doing our production testing on the DP83865 we are seeing some boards that will not establish a link and other boards that we are seeing receive CRC errors from the…
Other Parts Discussed in Thread: DP83865 I am using DP83865 and i have 1Gb link problem.
I changed BG_REF pin resistor from 9.76kOhm to 6.7kOhm and
i get a good 1Gb link.
Is there any idea that what was cause of 1Gb link problem
and why i get good link…
Other Parts Discussed in Thread: DP83865 Hi Support,
We use your PHY dp83865 in one of our boards, in RGMII 1000Mbps mode. I see that when testing for the PHY loopback mode, in some of the received packets, the CRC bytes (the last four bytes of the Ethernet…
