Overview
The ADF4107BCPZ-REEL is a high-performance frequency synthesizer produced by Analog Devices Inc. This component is designed to implement local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters. It features a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and programmable A and B counters. The synthesizer also includes a dual-modulus prescaler, enabling the implementation of an N divider. It can be used to create a complete phase-locked loop (PLL) when combined with an external loop filter and voltage-controlled oscillator (VCO).
