Analog Devices ADF4158 Datasheet
The ADF4158 is a 6.1 GHz fractional‑N frequency synthesizer that provides frequency, phase, and waveform generation capabilities. It features a 25‑bit fixed modulus for sub‑hertz resolution, a low‑noise digital phase‑frequency detector, programmable charge pump, and a 3‑wire serial interface for register control.
The device operates from a 2.7 V‑3.3 V supply (AVDD/DVDD) with a Vp up to 5.5 V, supports automotive‑grade reliability, and offers multiple modulation and sweep modes such as FSK, PSK, sawtooth, and triangular waveforms.
