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