## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Management Issues:
- Pitfall : Inadequate power supply design leading to voltage droops during high-processing loads
- Solution : Implement dedicated power planes with proper decoupling capacitors (recommended: 10μF bulk + 0.1μF ceramic per power pin)
Thermal Management:
- Pitfall : Insufficient heat dissipation causing thermal throttling or component failure
- Solution : Incorporate adequate heatsinking and consider forced air cooling for continuous full-load operation
Clock Distribution:
- Pitfall : Clock jitter affecting compression quality and system stability
- Solution : Use low-jitter clock sources and maintain proper clock signal integrity through controlled impedance routing
### Compatibility Issues with Other Components
Memory Interface:
- DDR SDRAM Compatibility : Requires careful timing analysis with compatible DDR memory controllers
- Solution : Use manufacturer-recommended memory devices and follow strict timing constraints
Host Processor Interface:
- Bus Compatibility Issues : Potential conflicts with 32-bit PCI bus implementations
- Solution : Ensure proper bus enumeration and configuration space mapping
Video Interface Timing:
- HD-SDI Integration : Requires precise clock domain crossing between video interfaces
- Solution : Implement robust synchronization circuits and phase-locked loops
