AD9854 Signal Generator Module High Speed DDS Module Signal

The AD9854 digital frequency synthesizer is a highly integrated device that uses advanced DDS technology and built-in two high-speed, high-performance quadrature DAC to form a digitally programmable 1 and Q frequency synthesizer. Using a precision clock source as a reference, the AD9854 can produce highly stable frequency phase, amplitude programmable sine and cosine outputs, and can be used as an agile L0 in communications, radar and many other applications.
The innovative high-speed DDS core provides 48-bit frequency resolution (with 300 MHz SYSCLK, the tuning resolution is 1μHz) Maintaining 17 bits ensures that the device has excellent spurious-free dynamic range (SFDR).
Support external signal input, high-performance DDS sine wave signal generator, high order elliptic filter, low-noise voltage regulator chip, etc.
Applicable to frequency signal generation, sine wave, square wave signal generation, sensor excitation.
Signal Characteristics: the sine wave square wave has no coupling output; the output has its own DC component. If it is connected to the radio frequency equipment, please add a DC blocker, or you can directly measure it with an oscilloscope. Square wave duty cycle adjustable range 5%-95% Specification:
