Register 0x01A9—FTW0 (Frequency Tuning Word) (Continued)

Bits  
Bit Name  
Description  
[31:24]  
FTW0  
These registers contain the FTW (frequency tuning word) for the DDS. The FTW determines the ratio  
of the AD9912 output frequency to its DAC system clock. Register 0x01A6 is the least significant  
byte of the FTW. Note that the power-up default is defined by start-up Pin S1 to Pin S4. Updates to  
the FTW results in an instantaneous frequency jump but no phase discontinuity.

DDS phase word  
Allows the user to vary the phase of the DDS output. See the Direct Digital Synthesizer section.  
Register 0x01AC is the least significant byte of the phase offset word (POW). Note that a momentary  
phase discontinuity may occur as the phase passes through 45° intervals.
