AD9850BRSZ

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. It operates with a 125 MHz master clock and provides a 10-bit DAC resolution. The 32-bit tuning word enables a frequency tuning resolution of 0.0291 Hz, and the output frequency can reach up to 62.5 MHz (half the reference clock). Five bits of phase modulation allow phase shifts in increments of 180°, 90°, 45°, 22.5°, and 11.25°. Typical power dissipation is 380 mW at 125 MHz with a 5V supply and 155 mW at 3.3V. The device offers an SFDR greater than 50 dB at 40 MHz AOUT. The AD9850BRSZ is housed in a 28-SSOP surface mount package and operates over a temperature range of -40°C to 85°C. It is suitable for frequency-agile clock generation, sine wave synthesis, and phase modulation applications.
