ADF4002BCPZ-RL

Overview

The ADF4002BCPZ-RL is an Integer-N phase detector and frequency synthesizer manufactured by Analog Devices Inc. It operates on a 2.7 V to 3.3 V power supply with a maximum phase detector frequency of 104 MHz. The device features a programmable charge pump with sink/source currents ranging from 625 µA to 5 mA, controlled via an external RSET resistor. It includes a 14-bit reference counter and a 13-bit N counter for frequency synthesis. The component is housed in a 20-lead LFCSP package and supports a -40°C to +85°C operating temperature range.

Feature Summary

Integrated low-noise digital phase frequency detector (PFD) and precision charge pump
Programmable charge pump currents selectable between 625 µA and 5 mA
Separate charge pump supply pin (VP) allows extended tuning voltage up to 5.5 V
3-wire serial interface for programming R and N counters

Applications

Clock conditioning
Clock generation
IF local oscillator (LO) generation

Procurement Notes

Verify the specific suffix RL against official documentation to confirm reel packaging specifications. Ensure compatibility with the 20-LFCSP footprint during procurement planning. Confirm that the B version industrial temperature rating meets system requirements.

Selection Notes

Select this component when implementing integer-N PLLs requiring a separate charge pump supply for high VCO tuning ranges. The device supports standalone PFD and charge pump operation by programming R and N dividers to 1. Verify input sensitivity requirements against the specified RF input range of 5 MHz to 400 MHz.

Part Context

The ADF4002 belongs to the ADF4002 series of frequency synthesizers. It is designed for wireless receiver and transmitter applications, functioning as a core component for local oscillators in upconversion and downconversion sections. The device integrates all necessary PLL components except the external loop filter and VCO.
