ADF4106SRUZ-EP

Overview

The ADF4106SRUZ-EP is an enhanced product integer-N PLL frequency synthesizer designed for defense and aerospace applications. It operates with a supply voltage of 2.7 V to 3.3 V and supports RF input frequencies from 500 MHz to 6.0 GHz. The device features a low-noise digital phase frequency detector, programmable charge pump currents (up to 5 mA), and a dual-modulus prescaler with selectable ratios of 8/9, 16/17, 32/33, or 64/65. It includes analog and digital lock detect functions, hardware/software power-down modes, and a 3-wire serial interface. The component is housed in a 16-lead TSSOP package and is qualified for military temperature ranges from −55°C to +125°C.

Feature Summary

• Supports defense and aerospace applications under AQEC standards with controlled manufacturing baseline
• Operates over military temperature range of −55°C to +125°C
• Features programmable dual-modulus prescaler (8/9, 16/17, 32/33, 64/65) and separate charge pump supply (VP) up to 5.5 V
• Includes analog and digital lock detect, hardware/software power-down mode, and 3-wire serial interface

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm packaging format; the 'Z' suffix indicates RoHS compliance. Confirm that the required temperature range aligns with the military specification of −55°C to +125°C. Ensure that the design accommodates the 16-lead TSSOP footprint and thermal requirements. Check for availability of qualification data if strict AQEC standards are mandated for the end application.

Selection Notes

Select this component when military-grade reliability and extended temperature operation are required. The separate VP pin allows tuning voltages up to 5.5 V even with a 3 V system supply. Ensure the RF input slew rate exceeds 320 V/µs for frequencies below 500 MHz. Verify that the external VCO and loop filter are compatible with the programmable charge pump current settings and prescaler ratios.

Part Context

The ADF4106SRUZ-EP belongs to the ADF4106-EP family of enhanced products. It shares core functionality with commercial variants but offers controlled manufacturing baselines, single assembly/fabrication sites, and product change notifications. This ensures long-term availability and consistency critical for defense and aerospace platforms where component obsolescence management is essential.

Replacement Considerations

The ADF4106SRU-EP is the non-RoHS compliant equivalent in the same package. Commercial versions like ADF4106BRUZ lack the military temperature rating and AQEC qualifications. Direct pin-compatible replacements within the enhanced product line include other packages such as the 20-lead LFCSP variant, provided thermal and layout constraints are met.
