GENERAL DESCRIPTION
The AD9912 is a direct digital synthesizer (DDS) featuring an
integrated 14-bit DAC. The AD9912 features a 48–bit
frequency tuning word (FTW) which can synthesize
frequencies in step sizes no larger than 4 uHz. Absolute
frequency accuracy can be achieved by adjusting the DAC
system clock.
The AD9912 also features an integrated system clock PLL,
which allows reference clocks as low as 25 MHz.
The AD9912 operates over an industrial temperature range,
spanning -40°C to +85°C.
