ADF4002BCPZ Datasheet PDF - ADI

●The ADF4002BCPZ is a Frequency Synthesizer that can be used to implement local oscillators in the up- 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. 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.

● Separate charge pump supply (VP) allows extended tuning voltage in 3V systems

● Programmable charge pump currents

● 3-wire serial interface

● Analog and digital lock detect

● Hardware and software power-down mode

● 104MHz phase detector
