As title In 51822 I know that we could generate 8Mhz via SPI, I want to know is there any other way could realize?

Please take a look at this project.
I couldn't build the project, is there exist version problem? =>(1)I can't build project directly (2)I port main function to my SDK project, it could be built, but signal seems always being pull high
As the readme says, the project is made for SDK 5.1.0, so if you try to compile it with a previous version, you'll most likely have to do some changes, in particular with regard to PIN names.
Due to a couple of PANs (see inline comments in the updated code), you'll also be limited to 4 MHz if you have a first revision chip.
IC mark QFAAC0 Is that the first revision?
Yes, it is. Refer to the migration whitepaper and the PCN for details on migration and changes: https://www.nordicsemi.com/eng/content/download/35525/598833/file/nWP-018_v1.1.pdf https://www.nordicsemi.com/eng/content/download/29460/494089/file/nRF51822-PCN%20v1%200.pdf
