SYSCLK cycles
1 To achieve the best possible phase noise, the largest amplitude clock possible should be used. Reducing the clock input amplitude reduces the phase noise
performance of the device.
2 Represents the cycle-to-cycle residual jitter from the comparator alone.
3 Represents the cycle-to-cycle residual jitter from the DDS core driving the comparator.
4 The maximum frequency of the serial I/O port refers to the maximum speed of the port during a write operation. During a register readback, the maximum port speed
is restricted to 2 Mbps.
5 Setup time refers to the TCSU (setup time of the falling edge of CS to the SCLK rising edge) and TDSU (setup time of the data change on SDIO to the SCLK rising edge).
6 Wake-up time refers to the recovery from analog power-down modes (see the Power-Down Functions section). 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 DACBP and that the recommended PLL loop filter values are used.
7 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.
8 SYNC_CLK = SYSCLK rate. For SYNC_CLK rates
≥ 50 MHz, the high speed sync enable bit, CFR2 [11], should be set.
9 This parameter indicates that the digital synchronization feature cannot overcome 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.
