This document introduces the features and characteristics of the ADF4210/ADF4211/ADF4212/ADF4213 four dual RF/IF PLL frequency synthesizers.
The ADF4210/ADF4211/ADF4212/ADF4213 are dual frequency synthesizers designed to implement local oscillators (LO) in the upconversion and downconversion sections of wireless receivers and transmitters. These devices can provide LO for both RF and IF sections and consist of a low-noise digital PFD, a precision charge pump, a programmable reference divider, and a dual-modulus prescaler. Control of all on-chip registers is achieved via a simple 3-wire serial interface. This manual is written in Chinese.
