제품 개요
ADF4159 is a 13GHz, fractional-N frequency synthesizer with modulation and both fast and slow waveform generation capability. The part uses a 25bit fixed modulus, allowing sub hertz frequency resolution. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. The Σ-Δ-based fractional interpolator allows programmable fractional-N division. It can be used to implement frequency shift keying (FSK) and phase shift keying (PSK) modulation. Frequency sweep modes are also available to generate various waveforms in the frequency domain, for example, saw tooth and triangular waveforms. Sweeps can be set to run automatically or with each step manually triggered by an external pulse. It features cycle slip reduction circuitry, which enables faster lock times without the need for modifications to the loop filter. It is used in application like FMCW radars, communications test equipment, communications infrastructure.
