@Mahihassi

Delivering an oscillation-capable crystal oscillator design that meets your exacting specifications is a challenge I'm thrilled to take on. As an electrical engineer with a Master's in Embedded Systems, I possess a comprehensive understanding of microcontrollers and FPGAs, which will be instrumental in the creation of a rock-solid MHz crystal oscillator. I have honed my skills by designing numerous low noise OCXOs and maximizing the performance of SC-cut crystals for radar and communication systems. This experience, coupled with my ability to identify and balance crucial design trade-offs quickly, makes me the perfect fit for this project. With an eye for detail, I will endeavor to provide not just a complete electrical design of the oscillator, but also transparent layout guidance minimizing stray capacitance and ensuring low EMI. Additionally, I'll provide simulation files that verify start-up margin, phase noise, and temperature stability, as well as a concise design note that compiles all calculations and test points for ease of quality assurance during production. Let's create an OCXO that not only meets but exceeds your expectations!

Hi Billd, When I saw your request for an MHz crystal oscillator (OCXO) design, it reminded me of other precision timing modules I’ve developed that combined ultra-stable SC-cut crystals, low-jitter amplifier stages, and carefully optimized PCB layouts for EMI suppression. One such project involved designing a communication-grade frequency reference that achieved excellent close-in phase noise and temperature stability, validated through SPICE simulation and real-world RF testing. ✅ With 11+ years of experience in oscillator design, RF front-end integration, and production-ready PCB layouts, I can deliver your OCXO concept from schematic and simulation through to layout guidance and test-ready documentation. Before I outline a detailed design plan, may I clarify a few points: 1. What is the exact target frequency range and tolerance required? 2. Do you have a preferred crystal supplier or should I propose a source? Two quick suggestions to strengthen reliability: ✅ Use an SC-cut crystal with tight aging specs to ensure long-term stability. ✅ Employ low-noise discrete transistor oscillation stages with proper oven control rather than relying solely on IC-based oscillator blocks. Freelancer doesn’t let me message first—please feel free to reach out, and I’d be glad to help engineer a rock-solid MHz OCXO design tailored to your RF system needs. Kind regards, Avi Gupta Quality is never an accident
