1.16. Guidelines: Board Design for ADC Reference Voltage Pin
The crosstalk requirement for analog to digital signal is -100 dB up to 2 GHz. There is no parallel routing between analog input signals and I/O traces. Route the VREF traces as adjacent as possible to REFGND.
If a REFGND plane is not possible, route the analog input signal as adjacent as possible to REFGND.
There is one ADC reference voltage pin in each MAX® 10 device. This pin uses REFGND as ground reference. Keep the trace resistance less than 0.8 Ω.
