- Digital frequency synthesis relies on stable crystal controlled reference frequency sources.
- A more used reference frequency is f h = 30 Hz.
- Typically a TDC uses a crystal oscillator reference frequency for good long term stability.
- This allows the synthesis of frequencies that are N / M times the reference frequency.
- It represents the difference of a measured frequency in parts per million from the reference frequency.
