- Digital interface level shifting for different voltage standards
### PCB Layout Recommendations
Power Distribution Network
- Use dedicated power planes for analog and digital sections
- Implement multiple decoupling capacitor tiers (bulk, ceramic, high-frequency)
- Place decoupling capacitors as close as possible to power pins
High-Speed Routing
- Route differential pairs with controlled impedance (100Ω differential)
- Maintain consistent spacing and avoid 90° turns
- Use via stitching for ground return paths
Thermal Management
- Provide adequate copper area for heat dissipation
- Consider thermal vias under package for heat transfer to ground plane
- Allow space for optional heatsink attachment if required
Component Placement
- Group related components (crystals, decoupling) near respective pins
- Minimize trace lengths for high-speed clock signals
- Separate analog and digital sections to reduce noise coupling
