The AD9851 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 digitally-programmable frequency synthesizer and clock generator function. When referenced to an accurate clock source, the AD9851 generates a stable frequency and phase-programmable digitized analog output sinewave. This sinewave can be used directly as a frequency source, or internally converted to a square wave for agile-clock generator applications. The AD9851's innovative high-speed DDS core provides a 32-bit frequency tuning word, which results in an output tuning resolution of 40 milli-Hertz, for a 180 MHz reference clock. The AD9851 contains a unique X6 reference clock multiplier circuit that obviates the need for a high-speed reference oscillator. The 6X PLL multiplier has minimal impact on SFDR and phase noise characteristics. The device provides 5-bits of digitally-controlled phase modulation which enables phase shifting of its output in increments of 180°, 90°, 45°, 22.5°, 11.25°, and any combination thereof. * 180 MHz Clock Rate with Selectable 6x Reference Clock Multiplier * On-Chip High Performance 10-Bit DAC and High Speed Comparator with Hysteresis * SFDR >43 dB @ 70 MHz AOUT * 32-Bit Frequency Tuning Word * 5-Bit Phase Modulation and Offset Capability https://elecena.pl/product/17777342/180-mhz-complete-dds-synthesizer 2021-04-18 https://elecena.pl/product/17777342/180-mhz-complete-dds-synthesizer 2025-01-21
