Other Parts Discussed in Thread: DP83869
Hello,
I am using the Ethernet Layer Transceiver DP83869HM in my new project to use it as SMGII to RGMII (MAC) interface. I want to use the two power supply configuration and according to the datasheet, I need to pull down the pin 23 (SUPPLYMODE_SEL).
My RGMII port between DP83869 and my Soc uses a 1V8 power supply rail. How can I define the VDDIO voltage? According to the datasheet, I need to select the VDDIO_SEL strap appropriately, but I cannot find how to do that.
According to this doubt, I need to supply 2V5 and 1V1 to the transceiver, but, is VDDIO internally generated or do I also need to supply the 1V8 to the transceiver?
Thank you very much in advance.
Have a nice day.
