General Description
The AD9850 is a highly integrated device that uses advanced
DDS technology coupled with an internal high speed, high
performance, D/A converter and comparator, to form a com-
plete digitally programmable frequency synthesizer and clock
generator function. When referenced to an accurate clock
source, the AD9850 generates a spectrally pure, frequency/
phase-programmable,
analog output sine wave. This sine wave
can be used directly as a frequency source or converted to a
square
wave for agile-clock generator applications. The AD
9850’s
innovative high speed DDS core provides a 32-bit frequency
tuning word, which results in an output tuning resolution of
0.0291 Hz, for a 125 MHz reference clock input.
