AD9833,pdf datasheet (CMOS 200

The AD9833 is a low power programmable waveform generator

capable of producing sine, triangular, and square wave outputs.

Waveform generaTIon is required in various types of sensing,

actuaTIon, and TIme domain reflectometry applicaTIons. The output

frequency and phase are software programmable, allowing easy

tuning. No external components are needed. The frequency registers

are 28 bits; with a 25 MHz clock rate, resolution of 0.1 Hz

can be achieved. Similarly, with a 1 MHz clock rate, the AD9833

can be tuned to 0.004 Hz resolution.
