国产化FMQL平台扩展多路高速时钟的方法OACSTPCD

The communication device,based on domestic FMQL as the main chip,needs to generate multiple high-speed clocks for other modules.The on-chip resources based on FMQL can generate several clocks,but there are some problems such as PL resource consump-tion,insufficient clock number,insufficient clock frequency,and insufficient flexibility in configuration.With the development of integrated circuits,using dedicated clock chips can effectively solve these problems.This paper proposes a method utilizing SI5341 and GM4526 clock chips to implement extended multi-channel high-speed clocks on the FMQL platform.The system design,hardware design and driver design of the method are introduced in this paper.The stability,practicability and flexibility of the method are verified by experiments.The method based on SI5341 and GM4526 to implement the extended multi-channel high-speed clock on the FMQL platform is stable,practical and flexible,providing reference for similar requirements.
