Part Number: AD9850
Function: CMOS, 125 MHz Complete DDS Synthesizer
Package: SSOP 28 Pin Type
Manufacturer: Analog Devices
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 complete, digitally programmable frequency synthesizer and clock generator function. When referenced to an accurate clock source, the device generates a spectrally pure, frequency/phase programmable, analog output sine wave.
This sine wave can be used directly as a frequency source, or it can be converted to a square wave for agile-clock generator applications. The AD9850’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.
