ADF4382BCCZ

ADF4382BCCZ is Analog Devices’ high‑performance fractional‑N phase‑locked loop (PLL) frequency synthesizer. It generates precise RF frequencies by locking a VCO to a programmable reference through a fractional divider, delivering fine frequency resolution with reduced spurs.
Key points
- Digital control: SPI interface to program modulus, division ratio, and fractional settings
- Fractional‑N with delta‑sigma arithmetic for improved close‑in phase noise
- PLL core with phase detector, charge pump, lock detect, and power‑down options
- Reference input for an external stable clock; suitable for various reference frequencies
- RF synthesis output designed to drive an external VCO/feedback network; packaging variant BCCZ denotes the RoHS‑compliant package
Typical applications
- Wireless transceivers, RF/microwave links, radar, and test equipment
- Clock and data recovery systems requiring flexible, low‑noise frequency synthesis
Note
- For exact frequency range, reference requirements, VCO options, spur/phase‑noise specs, and electrical characteristics, consult the ADF4382 datasheet and product page.
