RGMII voltage levels

calypso

Hello.
Can anybody comment on the issue regarding RGMII voltage levels?
What I mean is the schematic MB-JM3-RK3568-V11-20210412.pdf
The signals GMAC1_TXD0_M1, GMAC1_TXD1_M1 are based on the 3,3V power domain.
On the other hand the signals GMAC1_TXD2_M1, GMAC1_TXD3_M1 are based on the 1,8V power domain.
And all these four signals are wired directly to the U28 RTL8211F-CG.
As we can see the RTL8211F-CG is configured as "RGMII Power Source = 1,8V (default)".
So, is it possible to use RGMII TX 3,3V-levels with RTL8211F-CG 1,8V powered IOs?

Solved.
Dear support (if you exist at all).
Kindly look for the mistakes in the Core-3568J Product Specification.pdf (V1.0).
It contains wrong "IO Power domain" values in the table.

sorry, the io is 1.8V. please refer to Product SpecificationV2.1

There’s something deeply satisfying about shaving off 0.01 seconds in Speed Stars. It’s a game of inches, timing, and perfect execution — and it never gets old.

RGMII employs LVTTL or LVCMOS signals, which are digital signals with low logic voltages. 3.3V, 2.5V, or 1.8V, depending on the chip architecture or FPGA/ASIC platform utilized. However, many modern systems choose 1.8V to reduce power consumption and electromagnetic interference (EMI).

Oh, RGMII voltage levels, huh? Sounds like a super fun game figuring that out! Hope the image helps others dealing with similar hardware issues. Good luck to everyone diving into these speedstars[url=https://speedstars.xyz/]speedstars[/url] configurations!
