Other Parts Discussed in Thread: DP83869
On page 14 of the datasheet the following information can be found regarding series termination of the RGMII port:
This would imply that the series termination resistors are only on the RX pins of the port. Are they also included in the TX pins or will I need to add them external to the chip?
Also, what is the voltage domain of the RGMII signals? More specifically if I change the supply voltage on VDDIO from 2.5V to 3.3V will it impact the signaling levels of the RGMII interface? I plan to interface the RGMII of the DP83869HM to the RGMI port on another device where the voltage domain is 2.5V. Thanks
