ADF4106SCPZ-EP-R7

Overview

The ADF4106SCPZ-EP-R7 is an enhanced product PLL frequency synthesizer from Analog Devices, designed for defense and aerospace applications. It operates within a military temperature range of −55°C to +125°C and supports a 6.0 GHz bandwidth with a 2.7 V to 3.3 V power supply. The device features a programmable dual-modulus prescaler (8/9, 16/17, 32/33, 64/65), a precision charge pump, and a 3-wire serial interface. Packaged in a 20-lead LFCSP, it includes hardware and software power-down modes and separate analog/digital ground planes for noise isolation.

Feature Summary

• Military-grade reliability with controlled manufacturing baseline and one assembly/test site
• 6.0 GHz RF input bandwidth with normalized phase noise floor of −223 dBc/Hz
• Programmable dual-modulus prescaler options: 8/9, 16/17, 32/33, 64/65
• Separate charge pump supply (VP) allows extended tuning voltage up to 5.5 V

Applications

• Broadband wireless access systems
• Satellite communication systems
• Instrumentation and measurement equipment
• Wireless LAN infrastructure
• Base stations for wireless radios

Procurement Notes

Verify the EP suffix indicates Enhanced Product status suitable for defense/aerospace. Confirm the R7 suffix denotes reel packaging. Check for qualification data availability upon request as specified in the datasheet. Ensure compliance with controlled manufacturing baseline requirements for your specific application needs.

Selection Notes

Select this component when military temperature operation (−55°C to +125°C) is required. The LFCSP package offers thermal advantages via the exposed pad connected to AGND. Consider the separate VP pin if higher VCO tuning voltages are needed beyond the standard 3.3 V supply. Verify that the 6.0 GHz maximum RF input frequency meets system specifications.

Part Context

This part belongs to the ADF4106 family of integer-N PLL frequency synthesizers. The SCPZ-EP variant specifically denotes the Lead Frame Chip Scale Package with RoHS compliance and Enhanced Product status. It shares functional similarities with commercial variants but differs in temperature range and manufacturing controls.

Replacement Considerations

Direct replacements include other ADF4106-EP variants such as ADF4106SRUZ-EP-R7 (TSSOP package). Ensure package compatibility and verify that the replacement maintains the required military temperature rating and enhanced product qualifications.
