## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Sequencing:
- Pitfall : Improper power-up sequence can cause latch-up or permanent damage
- Solution : Implement strict power sequencing control using dedicated power management ICs
Signal Integrity Issues:
- Pitfall : High-speed digital signals susceptible to reflection and crosstalk
- Solution : Use controlled impedance routing and proper termination techniques
Thermal Management:
- Pitfall : Inadequate heat dissipation leading to thermal throttling or premature failure
- Solution : Implement sufficient copper pours and consider active cooling for high-load scenarios
### Compatibility Issues with Other Components
Memory Interface:
- Requires compatible DDR3/DDR4 memory with specific timing characteristics
- Ensure memory controller settings match the FLI8548HLFBE requirements
Video Input/Output Interfaces:
- HDMI/DisplayPort receivers must support required data rates and protocols
- Analog video components need proper impedance matching and filtering
Power Management:
- Voltage regulators must provide clean power with minimal ripple and noise
- Power sequencing controllers must be compatible with the chip's requirements
### PCB Layout Recommendations
Power Distribution:
- Use separate power planes for digital and analog supplies
- Implement multiple vias for low-impedance power connections
- Place decoupling capacitors close to power pins (100nF ceramic + 10μF tantalum)
High-Speed Signal Routing:
- Maintain consistent impedance for differential pairs (typically 100Ω)
- Keep high-speed traces as short as possible with minimal vias
- Route clock signals with extra care to minimize jitter
Thermal Management:
- Use thermal vias under the package to transfer heat to internal ground planes
- Consider adding a thermal pad or heatsink for high-power
