AD9912 has a 48-bit frequency tuning word (FTW) that can synthesize frequencies in steps no greater than 4 μhz. Absolute frequency accuracy can be achieved by adjusting the DAC system clock. The AD9912 also has an integrated system clock phase-locked loop (PLL) that enables system clock inputs down to 25 MHz. The operating temperature range of the AD9912 is an industrial temperature range of 40°C to 85°C.
