Design Recommendations

Allow for 2 minutes of warm-up time before frequency accuracy is within ±0.1ppm. Use clean 5V power with minimal ripple for optimal phase noise. Place VCO input (0–5V) on a stable analog line with 100kΩ input impedance. Avoid proximity to high-EMI components and provide thermal isolation if operating in tight enclosures.
