Overview
The ADF4107BRU-REEL is a 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, programmable A and B counters, and a dual-modulus prescaler (P/P + 1). The ADF4107 can be used to create a complete phase-locked loop (PLL) when combined with an external loop filter and voltage-controlled oscillator (VCO).
