The ADF4153 is a fractional-N frequency synthesizer that implements local oscillators in the upconversion and downconversion sections of wireless receivers. It features RF bandwidth up to 4 GHz, 2.7 V to 3.3 V power supply, programmable fractional modulus, programmable charge pump currents, 3-wire serial interface, and more.
The ADF4153 is a fractional‑N frequency synthesizer designed for use in local oscillators of wireless receivers and transmitters. It integrates a digital phase‑frequency detector, charge pump, and programmable reference divider, and can be configured via a simple 3‑wire serial interface.
The handbook details the device’s features such as a 2.7 V‑3.3 V supply range, extended tuning voltage, programmable fractional modulus, and power‑down mode. It includes specifications, timing diagrams, absolute maximum ratings, pin configurations for TSSOP and LFCSP packages, typical performance curves, circuit description, and ordering information.
