Our Ethernet PHYs have a standard set of registers, 0x0-0x1F, that can be accessed in a straight forward fashion. Registers beyond 0x1F require a different approach to access.
This FAQ is intended to provide a few examples on how to read/write these registers…
Part Number: DP83869HM
DP83869HM needs an additional register to be written to enable CLKOUT modification. By default, this signal is a buffered version of the XI signal. Reg 0xC6 must have 0x10 written in order for the value in Reg 0x170[12:8] to take…
Other Parts Discussed in Thread: DP83869 , DP83825 Summary:
All of our Industrial Ethernet PHYs support Transformer-less Operation via Capacitive Coupling except for the DP83867.
