ADF4002SRU-EP-RL7

Overview

The ADF4002SRU-EP-RL7 is an enhanced product phase detector and frequency synthesizer from Analog Devices, designed for defense and aerospace applications under the AQEC standard. It operates within a military temperature range of −55°C to +125°C and utilizes a 16-lead TSSOP package. The device features a low-noise digital phase frequency detector with a maximum frequency of 104 MHz, a precision charge pump with programmable currents up to 5 mA, and a 14-bit reference counter. It supports a 2.7 V to 3.3 V power supply with a separate charge pump supply (VP) allowing extended tuning voltage up to 5.5 V.

Feature Summary

• Military-grade operation with a temperature range of −55°C to +125°C
• 104 MHz phase frequency detector and programmable charge pump currents (625 µA to 5 mA)
• Separate charge pump supply (VP) supporting up to 5.5 V for extended tuning
• Controlled manufacturing baseline with one assembly/test site and one fabrication site

Applications

• Clock conditioning
• Clock generation
• IF LO generation in wireless receivers and transmitters

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format. The -RL7 suffix indicates reel packaging, while other variants may use tube packaging. Confirm the enhanced product designation ensures compliance with the controlled manufacturing baseline and qualification data requirements necessary for defense and aerospace projects.

Selection Notes

Select this component when military temperature stability and controlled production sources are mandatory. Ensure the external loop filter and VCO support the required RF input frequency range of 5 MHz to 400 MHz. Verify that the system design accommodates the separate VP supply pin if high tuning voltages exceeding AVDD are needed for the VCO.

Part Context

This part belongs to the ADF4002-EP family, which represents the enhanced product version of the standard ADF4002. Unlike commercial variants, the EP version guarantees a single fabrication and assembly site, providing traceability and stability critical for long-life defense and aerospace systems.

Replacement Considerations

Standard ADF4002BRUZ or ADF4002BCPZ parts do not meet the military temperature range or controlled manufacturing requirements. Direct replacement requires another ADF4002-EP variant with compatible packaging.
