ADI ADF4158CCPZ

Дробный N-синтезатор (RF)ДаCMOS, TTLЧасы

Overview

The ADF4158CCPZ is a 6.1GHz fractional-N Frequency Synthesizer with modulation and waveform generation capability. It contains a 25-bit fixed modulus, allowing subhertz resolution at 6.1GHz. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump and a programmable reference divider. There is a sigma-delta (Σ-Δ) based fractional interpolator to allow programmable fractional-N division. The INT and FRAC registers define an overall N-divider as N = INT + (FRAC/225). The ADF4158CCPZ can be used to implement frequency shift keying (FSK) and phase shift keying (PSK) modulation. There are also a number of frequency sweep modes available, which generate various waveforms in the frequency domain, for example, sawtooth and triangular waveforms. Sweeps can be set to run automatically, or each step manually triggered by an external pulse.
