There are several critical signals which require specific care during board design:

1. Analog input and clock signals
   • Traces should be as short as possible and vias should be avoided where possible to minimize impedance discontinuities.
   • Traces should be routed using loosely coupled 100-Ω differential traces.
   • Differential trace lengths should be matched as close as possible to minimize phase imbalance and HD2 degradation.
2. Digital JESD204B output interface
   • Traces should be routed using tightly coupled 100-Ω differential traces.
3. Power and ground connections
   • Provide low resistance connection paths to all power and ground pins.
   • Use power and ground planes instead of traces.
   • Avoid narrow, isolated paths which increase the connection resistance.
   • Use a signal/ground/power circuit board stackup to maximize coupling between the ground and power plane.
