- Implement multiple decoupling capacitors (0.1μF, 1μF, 10μF) in close proximity to power pins
- Ensure adequate via stitching for power and ground planes
Signal Routing:
- High-speed differential pairs (≥ 1 Gbps) require length matching (±5 mil tolerance)
- Maintain consistent characteristic impedance (typically
