I cannot find the current requirements for the VIO-SD and VIO-RF inputs on the IW416. Section 9.6 shows all of the other rails except these two. Appreciate any help
Hi Iain,
Actually , you can check it's reference design.
For example, RD-IW416-QFN-WIB3-2A-V2 design files.
VIO_SD pin can be 1.8V or 3.3V, which is determined by platform side.
Hope above information is helpful to you!
Have a good day!
