16.000MHz crystal oscillator key parameters
Parameters that need to be focused on when selecting:
| Parameter | Typical Value | Importance |
| Frequency Tolerance | ±10ppm to ±50ppm | Affects timing accuracy |
| Load Capacitance (CL) | 8pF, 12pF, 18pF, 20pF | Must match circuit design |
| ESR (Equivalent Series Resistance) | 50Ω to 100Ω | Impacts oscillator startup |
| Operating Temperature | -20°C to +70°C (Commercial) | Critical for harsh environments |
| -40°C to +85°C (Industrial) | ||
| Aging Rate | ±3ppm/year | Long-term stability |
Importance of Load Capacitance
16MHz crystal oscillator needs External matching capacitors (C1 & C2 ) are used to stabilize the oscillation. The actual load capacitance calculation formula is:
- If the specification requires CL=18pF, it is recommended to use C1=C2=36pF (Assuming stray capacitance 3pF)
- Wrong capacitance value will cause frequency deviation or failure to oscillate
Typical Application of 16MHz Crystal Oscillator
1. Microcontroller (MCU) and embedded systems
