1 The gain value for VCO range Setting 5 is measured at 1000 MHz.

2 Wake-up time refers to the recovery from analog power-down. The longest time required is for the Reference Clock Multiplier PLL to relock to the reference. The wake-

up time assumes there is no capacitor on DAC_BP and that the recommended PLL loop filter values are used.

3 SYSCLK cycle refers to the actual clock frequency used on-chip by the DDS. If the reference clock multiplier is used to multiply the external reference clock frequency,

the SYSCLK frequency is the external frequency multiplied by the reference clock multiplication factor. If the reference clock multiplier is not used, the SYSCLK

frequency is the same as the external reference clock frequency.
