ADF4002SRUZ-EP-RL7

Overview

The ADF4002SRUZ-EP-RL7 is an enhanced product 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 supports a 400 MHz bandwidth with a 2.7 V to 3.3 V power supply. The device features a separate charge pump supply (VP) allowing extended tuning voltage up to 5.5 V in 3 V systems. Key electrical parameters include a programmable charge pump current ranging from 625 µA to 5 mA, a phase frequency detector frequency of 104 MHz, and normalized phase noise floor of −222 dBc/Hz. It utilizes a 3-wire serial interface for control.

Feature Summary

• Military-grade reliability with controlled manufacturing baseline and single assembly/fabrication sites
• Separate VP supply enables extended tuning voltage up to 5.5 V while operating on 3 V logic
• Programmable charge pump currents with high value of 5 mA and low value of 625 µA
• Low noise performance with normalized 1/f noise of −119 dBc/Hz at 10 kHz offset

Applications

• Clock conditioning for high-performance systems
• Clock generation in wireless transceivers
• IF local oscillator (LO) generation in upconversion/downconversion sections

Procurement Notes

Verify that the ordering suffix -RL7 corresponds to reel packaging as indicated in the official Analog Devices ordering guide. Confirm the Z suffix denotes RoHS compliance. Ensure procurement channels provide qualification data available upon request, which is critical for defense and aerospace sourcing requirements.

Selection Notes

Select this component when military temperature operation (-55°C to +125°C) and enhanced product controls are required. The separate VP pin allows driving VCOs with higher tuning voltages than the AVDD supply. Ensure the external RSET resistor is selected to achieve the desired charge pump current, noting the range is 3.0 kΩ to 11 kΩ for optimal accuracy.

Part Context

This part belongs to the ADF4002-EP Enhanced Product family, specifically tailored for defense and aerospace markets. It shares core functionality with the commercial ADF4002 but includes controlled manufacturing baselines and one assembly/test site. The SRU package variant indicates a TSSOP-16 form factor, distinct from other package options like LFCSP or CPZ.

Replacement Considerations

Direct replacements must be from the ADF4002-EP series to maintain military qualification. Non-EP versions lack the controlled manufacturing baseline and specific temperature range guarantees. Verify package compatibility (RU-16 TSSOP) and ensure the substitute supports the required VP supply voltage if extended tuning is needed.
