The ADF4360-2 is a fully integrated integer-N synthesizer and voltage-controlled oscillator (VCO) designed for a center frequency of 2000 MHz. In addition, a divide-by-2 option is available, whereby the user gets an RF output of between 925 MHz and 1085 MHz. Control of all the on-chip registers is through a simple 3-wire interface.
The ADF4360-2 is a fully integrated integer‑N synthesizer and voltage‑controlled oscillator (VCO) covering 1850 MHz to 2170 MHz, with an optional divide‑by‑2 output of 925 MHz to 1085 MHz. It operates from a 3.0 V to 3.6 V supply, supports 1.8 V logic, and is programmed via a simple 3‑wire serial interface.
