AD9912 is a direct digital synthesizer (DDS) with an integrated 14 bit to analog converter (DAC). The characteristic of AD9912 is a 48 bit frequency tunable word (FTW), which can synthesize a step size of no more than 4 μ The frequency of Hz. By adjusting the DAC system clock, absolute frequency accuracy can be achieved.

The AD9912 also features an integrated system clock phase locked loop (PLL) that allows the system clock input to be as low as 25 MHz.

AD9912 operates within the industrial temperature range, from -40 ° C to+85 ° C.

40 MHz offset: −161 dBc/Hz
