High precision open hardware clocks using multi-mode crystal oscillators
Very precise clocks have many different use cases, but they are complex to make and expensive to buy - leaving high precision timing out of reach for many. Currently, there are no open hardware designs capable of delivering so called "Stratum 2" accuracy.
This project will design and build an open hardware clock exploiting the properties of multi-mode crystal oscillators using modern numerical methods for frequency stabilization. A Field-Programmable Gate Array (FPGA) will be used for digital signal processing functions, multiple Proportional-Integral-Derivative (PID) control loops, and executing all necessary calculations needed for dynamic, real-time frequency corrections. High-Level Synthesis (HLS) code will be developed using the CflexHDL+PipelineC toolset, in order to validate and further mature that emerging design flow for signal processing applications.
