Analog Devices ADF4252 Datasheet Rev B
The ADF4252 frequency synthesizer integrates a low‑noise digital phase‑frequency detector, programmable charge pump, and dual‑modulus prescaler for both RF and IF sections. It supports a 3 GHz fractional‑N RF synthesizer and a 1.2 GHz integer‑N IF synthesizer, controlled via a 3‑wire serial interface.
Typical applications include base stations, wireless handsets, LANs, test equipment, and CATV. The device operates from 2.7 V to 3.3 V, offers power‑down mode, and includes lock‑detect and digital lock‑detect features.
