ADI ADF4002BRUZ

Синтезатор тактовой/частотной частоты (RF), фазовый детекторДа с байпасомCMOS, TTLЧасы

Overview

The ADF4002BRUZ is a Phase Detector/Frequency Synthesizer used to implement local oscillators in the up conversion and down conversion sections of wireless receivers and transmitters. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider and programmable N divider. Separate charge pump supply (VP) allows extended tuning voltage in 3V systems. The 14-bit reference counter (R counter) allows selectable REFIN frequencies at the PFD input. A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). In addition, by programming R and N to 1, the device can be used as a standalone PFD and charge pump. The ADF4002BRUZ is ideal to use in clock conditioning and clock generation as well as IF LO generation.
