| Abstract: | Aiming at the requirement of high reliability and high stability clock source, an embedded clock generator based on Raspberry Pi is designed. Using 3B+ Raspberry Pi embedded control platform and Qt development tool, ADF4356 frequency synthesizer is controlled by RS485 communication bus to synthesize target frequency. The test results show that the control platform of the clock generator is stable and reliable. It can control the ADF4356 frequency synthesizer to synthesize the frequency in the range of 53.125-6 800 MHz, the transition time is less than 100 ps, and the RMS jitter is less than 5 ps, which provides some practical support for the design and implementation of more functional clock generators. |
