## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Management Issues:
- Pitfall : Inadequate decoupling causing voltage droop during high computational loads
- Solution : Implement multi-stage decoupling with 100nF, 10μF, and 100μF capacitors distributed around the package
Thermal Management:
- Pitfall : Overheating during sustained 4K processing operations
- Solution : Incorporate thermal vias under the package and consider active cooling for enclosed environments
Clock Distribution:
- Pitfall : Clock jitter affecting compression quality
- Solution : Use low-jitter clock sources and maintain proper clock tree symmetry
### Compatibility Issues
Memory Interface:
- DDR SDRAM Compatibility : Requires careful timing analysis with memory controller
- Solution : Use manufacturer-recommended memory parts and follow strict PCB layout guidelines
Video Interface Standards:
- HD-SDI Integration : May require external serializers/deserializers
- Solution : Implement proper impedance matching and equalization circuits
Power Supply Sequencing:
- Critical Issue : Improper sequencing can damage the device
- Solution : Follow strict power-up sequence: Core (1.2V) → I/O (3.3V) → Analog (1.8V)
