ADF4002 Datasheet Phase Detector/frequency Synthesizer

Manufacturer: Analog Devices

Overview: Data Sheet Phase Detector/Frequency Synthesizer ADF4002.

General Description

The ADF4002 frequency synthesizer is used to implement local oscillators in the upconversion and downconversion 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.

Key Features

  • 400 MHz bandwidth 2.7 V to 3.3 V power supply Separate charge pump supply (VP) allows extended tuning voltage in 3 V systems Programmable charge pump currents 3-wire serial interface Analog and digital lock detect Hardware and software power-down mode 104 MHz phase detector.
