ADF4106SCPZ-EP

Overview

The ADF4106SCPZ-EP is an enhanced product PLL frequency synthesizer designed for defense and aerospace applications. It operates with a 6.0 GHz bandwidth and supports power supplies from 2.7 V to 3.3 V, featuring a separate charge pump supply (VP) up to 5.5 V. The device includes a low noise digital phase frequency detector, precision charge pump, programmable reference divider, and dual-modulus prescaler. It functions within a military temperature range of −55°C to +125°C and utilizes a 20-lead LFCSP package.

Feature Summary

• Military temperature range operation from −55°C to +125°C
• Supports defense and aerospace applications with controlled manufacturing baseline
• 6.0 GHz RF input bandwidth with programmable dual-modulus prescaler options
• Separate VP supply allows extended tuning voltage in 3 V systems

Applications

• Broadband wireless access
• Satellite systems
• Instrumentation
• Wireless LANs
• Base stations for wireless radios

Procurement Notes

Verify the specific suffix requirements for packaging and RoHS compliance when ordering. The SCPZ variant indicates a lead frame chip scale package that is RoHS compliant. Ensure the procurement channel provides qualification data and product change notifications as required for enhanced product lines. Confirm the availability of controlled manufacturing baseline documentation for the specific lot.

Selection Notes

Select the ADF4106SCPZ-EP for designs requiring military-grade reliability and wide temperature tolerance. The 20-lead LFCSP package offers thermal advantages but requires careful PCB design regarding the exposed pad connection to AGND. Consider the separate VP pin if the application demands tuning voltages exceeding the standard AVDD level. Verify that the system architecture can accommodate the 3-wire serial interface timing constraints.

Part Context

This component belongs to the ADF4106-EP family, which is an enhanced version of the standard ADF4106 frequency synthesizer. The EP designation signifies qualification for harsh environments, including controlled fabrication sites and one assembly/test site. It shares functional similarities with the commercial ADF4106BRUZ variants but differs in operating temperature range and manufacturing controls.

Replacement Considerations

The ADF4106SRU-EP serves as a pin-compatible alternative in a 16-lead TSSOP package. Both parts share the same electrical specifications and military temperature rating. Selection between them depends on the available footprint and thermal management strategy on the printed circuit board.
