Is it possible not to place silkscreen position numbers on a PCB? The silkscreen position number is mainly for convenience during manual soldering or prototype debugging stages, as it visually indicates the component positions, facilitating assembly, maintenance, and testing, primarily used in the prototype phase. It is indeed possible to manage without position numbers when … Read more

[Conclusion] General IO cannot be directly used as a clock input for PLL; dedicated clock pins can be used instead. General IO can be connected to the PLL clock input through a BUFG, but the PLL settings must be modified to select “No Buffer” for the input clock option. The specific internal layout can be … Read more
