Design Recommendations
Allow a warm-up period of 5 minutes at 25°C to meet ±0.1 ppm stability. Use well-filtered 3.3V supply with bypass capacitors close to Vcc pins. Keep control voltage (VCO) lines clean and isolated. For precision clock systems, consider thermal isolation from heat sources on PCB.
