## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Design
*Pitfall*: Inadequate power supply sequencing and decoupling
*Solution*: Implement proper power-on sequencing and use recommended decoupling capacitors (10μF bulk + 0.1μF ceramic per power pin)
Clock Distribution
*Pitfall*: Poor clock signal integrity affecting video synchronization
*Solution*: Use controlled impedance traces for clock signals and maintain proper termination
Thermal Management
*Pitfall*: Insufficient heat dissipation in high-ambient environments
*Solution*: Incorporate adequate thermal vias and consider heatsinking for continuous full-load operation
### Compatibility Issues with Other Components
Input/Output Interfaces
- SDI Receivers : Compatible with standard SDI deserializers (DS25BR110, DS25CP104)
- FPGA/Processors : Requires proper level translation for 1.8V/3.3V interfaces
- Memory Interfaces : External EEPROM for configuration must use compatible I²C interface
Power Management
- Voltage Regulators : Requires precise 1.8V and 3.3V supplies with adequate current capability
- Power Sequencing : Must follow manufacturer-recommended sequence to prevent latch-up
### PCB Layout Recommendations
Power Distribution
- Use separate power planes for analog and digital supplies
- Implement star-point grounding for sensitive analog circuits
- Place decoupling capacitors as close as possible to power pins
Signal Integrity
- Maintain 100Ω differential impedance for SDI pairs
- Keep SDI traces away from noisy digital signals and clock sources
- Use ground shielding between critical signal paths
BGA Package Considerations
- Utilize 4-6 layer PCB with dedicated power and ground planes
- Implement proper via-in-pad technology for BGA escape routing
- Ensure
