Overview
The ADF4153BRUZ from Analog Devices Inc. is a fractional-N frequency synthesizer designed to implement local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters. This device integrates a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. It also features a Σ-Δ based fractional interpolator, enabling programmable fractional-N division. A complete phase-locked loop (PLL) can be implemented when used with an external loop filter and a voltage-controlled oscillator (VCO).
