Product details
Overview
ADF4002SRUZ-EP from Analog Devices is a radiation-hardened, enhanced-product-grade phase-locked loop (PLL) frequency synthesizer with integrated phase frequency detector (PFD) and programmable charge pump. It operates from −55°C to +125°C, supports 5–400 MHz RF input, features 104 MHz PFD frequency, 2.7–3.3 V dual supply, and separate VP pin enabling up to 5.5 V tuning voltage for VCO control in 3 V systems.
For engineers reviewing the ADF4002SRUZ-EP datasheet, ADF4002SRUZ-EP pinout, ADF4002SRUZ-EP application, or ADF4002SRUZ-EP equivalent, this page delivers verified military-grade PLL specifications, TSSOP-16 pin mapping, lock-detect functionality, serial interface timing, and drop-in alternatives for defense/aerospace clock synthesis and IF LO generation.
Technical Context
The ADF4002SRUZ-EP implements a fully digital PFD with 2.9 ns antibacklash pulse width and a precision current-steering charge pump whose sink/source current is set via RSET (5.1 kΩ nominal), delivering programmable ICP from 625 µA to 5 mA. Its 14-bit R counter and 13-bit N counter enable flexible reference and feedback division for wideband frequency planning.
It integrates analog and digital lock detect outputs, hardware/software power-down modes, and a multiplexer output (MUXOUT) that selects between lock status, scaled RF, or scaled REFIN - all operating across the full −55°C to +125°C military temperature range with controlled manufacturing baseline per AQEC standard.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PLL frequency synthesizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADF4153BRUZ | Higher 4 GHz RF input, integrated VCO, no VP pin, 1.8 V logic compatible. | Single-chip solution for compact 2.4 GHz ISM band radios; lacks extended tuning voltage and military temp range. | Choose ADF4153BRUZ only if VCO integration and lower supply voltage outweigh need for −55°C operation and 5 V tuning headroom. |
| LTC6946IUF-4#PBF | Integrated VCO, wider 750 MHz–4.4 GHz output, fractional-N architecture, no discrete R/N counters. | Superior spurious performance for wideband comms; requires different loop filter design and lacks standalone PFD mode. | Choose LTC6946IUF-4#PBF when ultra-low close-in phase noise and fractional division are mandatory - not for legacy integer-N or PFD-only use cases. |

FAQ
What is the operating temperature range of the ADF4002SRUZ-EP?
The ADF4002SRUZ-EP is qualified for continuous operation from −55°C to +125°C, meeting AQEC standards for defense and aerospace applications. This extended range is achieved through controlled fabrication and assembly baselines, single-site manufacturing, and rigorous screening - unlike commercial-grade ADF4002 variants limited to −40°C to +85°C.
Does the ADF4002SRUZ-EP include an integrated VCO?
No, the ADF4002SRUZ-EP does not include an integrated VCO. It is a PLL frequency synthesizer core comprising a phase frequency detector, programmable dividers, and a precision charge pump - designed to drive an external VCO via the CP pin. This architecture provides full flexibility in VCO selection, tuning range, and noise performance.
How is the charge pump current configured on the ADF4002SRUZ-EP?
The ADF4002SRUZ-EP uses an external resistor (RSET) connected between Pin 1 and CPGND to set maximum charge pump current, with ICPMAX = 25.5 V / RSET. At 5.1 kΩ, it delivers 5 mA; scaling RSET adjusts ICP linearly down to 625 µA. Additional fine-tuning is possible via CPI[5:1] control bits in the 24-bit register.
What package type is used for the ADF4002SRUZ-EP?
The ADF4002SRUZ-EP is packaged in a 16-lead TSSOP (RU-16), JEDEC MO-153-AB compliant, with 0.65 mm lead pitch and dimensions of 5.00 mm × 4.40 mm × 1.20 mm. It is RoHS-compliant (indicated by the "Z" suffix) and features no exposed thermal pad - simplifying PCB layout for high-reliability military assemblies.
Can the ADF4002SRUZ-EP operate as a standalone phase frequency detector?
Yes, the ADF4002SRUZ-EP can operate as a standalone PFD and charge pump by programming both the R and N counters to 1. In this mode, it compares REFIN and RFIN directly, outputs error current on CP, and asserts lock detect - enabling use in custom PLL architectures or as a building block in hybrid analog-digital synthesizers.
