Product details
Overview
ADF4213BRUZ from Analog Devices is a dual RF/IF PLL frequency synthesizer designed for local oscillator generation in wireless transceivers, supporting RF input up to 3.0 GHz and IF input up to 1.0 GHz at 3 V operation, with programmable dual-modulus prescaler (8/9, 16/17, 32/33, 64/65), 3-wire serial interface, and analog/digital lock detect - deployed in GSM, WCDMA, and wireless LAN base stations.
For engineers reviewing the ADF4213BRUZ datasheet, ADF4213BRUZ pinout, ADF4213BRUZ application, or ADF4213BRUZ equivalent, key selection criteria include its 0.2–3.0 GHz RF input range, 6-bit RF A-counter + 12-bit RF B-counter architecture, separate VP1/VP2 charge pump supplies enabling 6 V tuning voltage in 3 V systems, and fastlock/power-down modes critical for time-sensitive RF subsystems.
Technical Context
The ADF4213BRUZ implements two independent PLL paths - one for RF (up to 3.0 GHz) and one for IF (up to 1.0 GHz) - each with dedicated phase-frequency detector (PFD), charge pump (ICP programmable from 625 µA to 5 mA), 14-bit R-counter, and dual-modulus prescaler. Its N-divider uses BP + A architecture where P = 8/9, 16/17, 32/33, or 64/65, A = 0–63, B = 3–8191.
It operates from 2.7 V to 5.5 V with separate analog/digital supply domains (VDD1/VDD2, VP1/VP2), supports CMOS/TTL REFIN inputs up to 115 MHz, and delivers phase noise of –89 dBc/Hz @ 1 kHz offset (900 MHz RF output, 200 kHz PFD), –88 dBc/Hz @ 1 kHz offset (2400 MHz RF output, 1 MHz PFD), and spurious levels down to –90 dBc.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Input Frequency | 0.2–3.0 GHz (3 V operation); enables direct synthesis for PCS, UMTS, and 2.4 GHz ISM band LO generation without harmonic mixing |
| IF Input Frequency | 0.06–1.0 GHz (3 V); supports IF-stage LO synthesis for zero-IF or low-IF receiver architectures |
| PFD Frequency Max | 55 MHz; sets upper bound on reference division ratio and loop bandwidth design flexibility |
| Charge Pump Current | Programmable 625 µA–5 mA (via RSET = 1.5–5.6 kΩ); allows optimization of loop filter dynamics and VCO tuning sensitivity |
| Power Supply Range | 2.7–5.5 V (VDD1/VDD2); compatible with both 3 V and 5 V system rails; VP1/VP2 support up to 6 V for extended VCO tuning range |
| Phase Noise Floor | –171 dBc/Hz @ 25 kHz PFD frequency; defines ultimate close-in noise floor limitation for high-sensitivity receivers |
| Spurious Performance | –90/–94 dBc @ 200/400 kHz offsets (2400 MHz RF); ensures compliance with spectral mask requirements in LTE/Wi-Fi coexistence scenarios |
Pinout & Package
TSSOP-20 (RU-20) package with 0.65 mm pitch; thermally enhanced layout with dedicated analog/digital ground pins (AGNDRF/DGNDRF/AGNDIF/DGNDIF) and isolated charge pump supplies (VP1/VP2) to minimize supply coupling in sensitive RF/IF paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 / VDD2 | RF and IF digital/analog power supplies | Must be equal (2.7–5.5 V); decoupling required per pin; separates RF/IF digital domains to reduce crosstalk |
| VP1 / VP2 | RF and IF charge pump analog supplies | Can exceed VDD by up to 3 V (max 6 V); enables full 0–6 V VCO tuning range in 3 V systems |
| RFIN / IFIN | Differential RF/IF input terminals | AC-coupled CML-compatible inputs; require external bias network per Figure 3; support square-wave or sine inputs |
| CPRF / CPIF | RF and IF charge pump outputs | Connect to external loop filters driving VCOs; current-sink/source capability defined by RSET resistor |
| REFIN | Reference clock input | CMOS/TTL-compatible (0–VDD); 100 kΩ internal termination; supports 0–115 MHz reference frequencies |
| CLK/DATA/LE | 3-wire serial interface | 24-bit shift register control; MSB-first loading; LE latches data into selected register (IF-R, IF-AB, RF-R, RF-AB) |
| MUXOUT | Configurable multiplexer output | Selectable via P3/P4/P11/P12 bits to monitor RF/IF lock detect, R/N counter outputs, or reference divider |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent PLL paths | Enables simultaneous RF and IF LO generation without external multiplexing or timing coordination overhead |
| Separate VP1/VP2 charge pump supplies | Allows 6 V tuning voltage headroom in 3 V systems - essential for wide-tuning-range VCOs in broadband radios |
| Programmable dual-modulus prescaler | Four selectable ratios (8/9, 16/17, 32/33, 64/65) enable optimal trade-off between resolution, speed, and spur performance across bands |
| Analog + digital lock detect | Dual lock indicators (open-drain analog LD + CMOS digital LD) simplify system-level status monitoring and fault recovery |
| Fastlock mode | Reduces frequency settling time to ~200 µs (900 MHz, 20 kHz loop BW), critical for TDD and burst-mode wireless protocols |
| Low-power sleep mode | 1 µA typical quiescent current enables rapid wake-up while preserving battery life in portable RF modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-path PLL synthesizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADF4212BRUZ | Lower RF max frequency (2.7 GHz vs. 3.0 GHz); identical IF range (1.0 GHz), same pinout and register map | Suitable for 2.6 GHz LTE-TDD and WiMAX bands but not 2.9–3.0 GHz 5G NR n77/n78 | Select when operating below 2.7 GHz to leverage identical layout and firmware with marginally lower cost |
| LMS6002DFN | Integrated transceiver (RF+IF+ADC/DAC); no external VCO required; higher integration but fixed architecture | Replaces entire RF front-end in SDR platforms; lacks standalone synthesizer flexibility and external VCO control | Choose for rapid prototyping of full transceivers; avoid when discrete VCO selection, custom loop filtering, or multi-VCO architectures are needed |
Compared with ADF4212BRUZ, the ADF4213BRUZ extends usable RF range by 300 MHz for 5G FR1 coverage, while LMS6002DFN trades synthesizer configurability for system-level integration - making ADF4213BRUZ optimal for high-performance, externally tuned RF designs requiring precise phase noise and spur control.

FAQ
What is the maximum RF input frequency supported by the ADF4213BRUZ at 3 V operation?
The ADF4213BRUZ supports an RF input frequency range of 0.2 GHz to 3.0 GHz when operated at 3 V (VDD1 = VDD2 = 3 V). This specification is explicitly stated in the "RF/IF CHARACTERISTICS (3 V)" table on page 2 of the datasheet under "ADF4213" row. The upper limit of 3.0 GHz enables direct synthesis for 5G NR n77/n78 bands and 2.4 GHz/5 GHz WLAN applications without harmonic multiplication.
Does the ADF4213BRUZ support independent configuration of its RF and IF PLL sections?
Yes, the ADF4213BRUZ provides fully independent RF and IF PLL paths, each with dedicated 14-bit R-counter, 6-bit A-counter, 12-bit B-counter, dual-modulus prescaler, phase-frequency detector, and charge pump. Register mapping (Table I) confirms separate latches for RF R, RF AB, IF R, and IF AB counters, allowing asynchronous frequency programming and lock detection per path - essential for dual-conversion architectures.
How is charge pump current programmed on the ADF4213BRUZ?
Charge pump current on the ADF4213BRUZ is set by an external resistor (RSET) connected between the RSET pin (Pin 14) and ground. The relationship is ICP MAX = 13.5 / RSET (kΩ), yielding 5 mA at RSET = 2.7 kΩ and 625 µA at RSET = 5.6 kΩ. Both RF and IF charge pumps share this setting, and the value is trimmed to ±3% accuracy over temperature and supply.
What package type is used for the ADF4213BRUZ, and what are its thermal characteristics?
The ADF4213BRUZ is packaged in a 20-lead TSSOP (RU-20) with θJA = 150.4°C/W. This thermally enhanced surface-mount package features exposed paddle grounding (per datasheet Absolute Maximum Ratings) and supports reflow soldering per JEDEC J-STD-020. Pin 1 is marked by a dot; the top-view pinout matches Figure 7 (TSSOP) on page 5 of the datasheet.
Can the ADF4213BRUZ generate both RF and IF LO signals simultaneously from a single reference clock?
Yes, the ADF4213BRUZ is explicitly designed for simultaneous dual-path LO synthesis. It accepts one REFIN signal (0–115 MHz) and independently divides it via separate 14-bit R-counters to feed two PFDs - one driving the RF N-divider (BP + A), the other the IF N-divider. This enables concurrent, non-interfering RF and IF LO outputs, as confirmed in the General Description and Functional Block Diagram.
