## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Design
- Pitfall : Inadequate power supply rejection leading to performance degradation
- Solution : Implement low-noise LDO regulators with proper decoupling (10 μF tantalum + 100 nF ceramic per supply pin)
Clock Generation
- Pitfall : Phase noise from clock source limiting dynamic performance
- Solution : Use ultra-low jitter clock sources (<100 fs RMS) with proper termination
Digital Interface
- Pitfall : JESD204B link training failures due to improper lane alignment
- Solution : Implement robust synchronization sequences and verify eye diagrams
### Compatibility Issues
Digital Processors
- Requires FPGAs or ASICs with JESD204B interface capability
- Compatible with Xilinx 7-series, Intel Stratix 10, and newer families
- May require interface conversion chips for legacy processors
Analog Front-End
- Optimal performance with differential drivers (ADA4945-1 recommended)
- Input common-mode voltage must match ADC requirements (typically 0.9V)
- Anti-aliasing filter design critical for preventing out-of-band noise folding
### PCB Layout Recommendations
Power Distribution
- Use separate power planes for analog, digital, and clock supplies
- Implement star-point grounding at ADC ground pins
- Place decoupling capacitors within 2 mm of supply pins
Signal Routing
- Route differential analog inputs with controlled 100 Ω impedance
- Maintain symmetrical trace lengths for differential pairs (±5 mil tolerance)
- Keep analog inputs away from digital and clock signals
Clock Routing
- Use dedicated ground plane for clock signals
- Implement proper termination at both source and ADC ends
- Avoid vias in clock transmission lines when possible
Thermal Management
- Provide adequate copper area for heat dissipation
- Consider thermal vias under package for improved heat transfer
- Ensure
