8.1.2.2 Sampling Clock

Applications operating with low input frequencies (such as DC to 20MHz) typically are less sensitive to performance degradation due to clock jitter. The internal ADC aperture jitter improves with faster rise and fall times (that is, square wave vs sine wave).

Termination of the clock input needs to be considered for long clock traces.
