Represents the cycle-to-cycle residual jitter from the comparator alone.
Wake-up time refers to the recovery from analog power-down modes (see section on Power-Down Modes of Operation). The primary limiting factor is the settling time of the PLL
multiplier in the reference circuitry. The wake-up time assumes there is no capacitor on DAC BP and that the recommended PLL loop filter values are used.
SYSCLK cycle refers to the clock frequency used on-chip to drive the DDS core. This is equal to the frequency of the reference source times the value of the PLL-based
reference clock multiplier.
SYNC_CLK = ¼ SYSCLK rate. Be sure the high speed sync enable bit, CFR2<11>, is programmed appropriately.
This parameter indicates that the digital synchronization feature cannot compensate for phase delays (timing skew) between system clock rising edges. If the system
clock edges are aligned, the synchronization function should not increase the skew between the two edges.
