ADF4159 Datasheet (Analog Devices) - Fractional-N Frequency Synthesizer

ADF4159, Fractional-N Frequency Synthesizer

The ADF4159 is a 13 GHz, fractional-N frequency synthesizer with modulation and both fast and slow waveform generation capability.

The part uses a 25-bit fixed modulus, allowing subhertz frequency resolution.

The ADF4159 consists of a low noise digital phase frequency detector (PFD), a precision cha
