## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Oscillator Startup Issues
- Problem : Oscillator fails to start or operates intermittently
- Solution :
- Ensure proper RC component selection (R ≥ 10kΩ, C ≥ 100pF)
- Add small capacitor (10-100pF) between OSC_IN and OSC_OUT for stability
- Include power supply decoupling close to the IC
Pitfall 2: Excessive Power Consumption
- Problem : Higher than expected current draw
- Solution :
- Limit clock frequency to minimum required for application
- Use higher value timing resistors within specified limits
- Ensure unused inputs are tied to VDD or GND (not left floating)
Pitfall 3: Timing In
