Overview
The ADF4156BRUZ-RL is a 6.2 GHz fractional-N frequency synthesizer produced by Analog Devices Inc. This device is designed to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. It features a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. The synthesizer includes a Σ-Δ based fractional interpolator, allowing for programmable fractional-N division. The device operates with a power supply ranging from 2.7 V to 3.3 V and can be powered down when not in use.
