The ADF4360-3 is a fully integrated integer-N synthesizer and voltage controlled oscillator (VCO). It has an output frequency range of 1600 MHz to 1950 MHz, a power supply of 3.0 V to 3.6 V, 1.8 V logic compatibility, a programmable dual-modulus prescaler with options of 8/9, 16/17, and 32/33, programmable output power level, a 3-wire serial interface, analog and digital lock detect, and hardware and software power-down mode. It is suitable for applications such as wireless handsets, test equipment, wireless LANs, and CATV equipment.
The ADF4360-3 is a fully integrated integer‑N synthesizer and voltage‑controlled oscillator (VCO) designed for a center frequency of 1750 MHz with an optional divide‑by‑2 mode that yields an RF output of 800 MHz to 975 MHz. Control of all on‑chip registers is performed through a simple 3‑wire serial interface, and the device operates from a 3.0 V to 3.6 V supply while supporting 1.8 V logic levels.
The document includes detailed specifications, pin configuration and function descriptions, timing characteristics, absolute maximum ratings, typical performance curves, application examples, and ordering information. It also provides noise performance, power‑down modes, and PCB design guidelines for the chip‑scale package.
