- Solution : Use tight-tolerance components and follow manufacturer's RC selection guidelines
- Pitfall : Crystal oscillator failure due to improper loading capacitors
- Solution : Calculate and use correct loading capacitors based on crystal specifications
Reset Circuit Problems
- Pitfall : Incomplete reset causing erratic counting
- Solution : Ensure reset pulse width exceeds minimum specification (typically 1μs)
- Pitfall : Reset signal noise causing unintended resets
- Solution : Implement proper filtering and use Schmitt trigger inputs
Power Supply Issues
- Pitfall : Voltage spikes affecting counter accuracy
- Solution : Implement proper decoupling capacitors (100nF ceramic close to VDD/VSS)
