Overview
The ADF4112BRUZ-REEL, produced by Analog Devices Inc., is a member of the ADF4110 family of frequency synthesizers. These devices are designed to implement local oscillators in the up-conversion and down-conversion sections of wireless communication systems. The ADF4112 is particularly suited for applications requiring high-frequency operation, with a maximum RF input frequency of 3.0 GHz. It operates on a power supply ranging from 2.7 V to 5.5 V and features a separate charge pump supply, allowing extended tuning voltage in 3 V systems.
