Product details
Overview
ADF7012BRUZ-RL7 from Analog Devices is a single-chip, low-power UHF FSK/GFSK/OOK/GOOK/ASK transmitter operating from 75 MHz to 1 GHz. It integrates a fractional-N PLL, VCO with external inductor tuning, programmable PA (−16 dBm to +14 dBm), and 3-wire serial interface. Designed for SRD applications, it delivers 12.5 dBm output at 868 MHz with 21 mA current draw and supports fast frequency hopping via sub-100 μs PLL lock.
For engineers reviewing the ADF7012BRUZ-RL7 datasheet, ADF7012BRUZ-RL7 pinout, ADF7012BRUZ-RL7 application, or ADF7012BRUZ-RL7 equivalent, key selection criteria include its 24-pin TSSOP package, 2.3–3.6 V supply range, 179.2 kbps FSK data rate, −80 dBc/Hz @ 5 kHz offset phase noise at 868 MHz, and support for FCC/ETSI-compliant wireless metering and secure keyless entry systems.
Technical Context
The ADF7012BRUZ-RL7 implements a fractional-N PLL architecture with Σ-Δ modulation enabling fine frequency resolution (<1 ppm steps) and rapid channel switching. Its VCO tuning voltage (VCOIN) ranges 0.3–2.0 V, with gain varying from 22 MHz/V at 315 MHz to 88 MHz/V at 915 MHz.
Modulation is fully configurable via four 32-bit registers: five schemes supported (FSK, GFSK, OOK, GOOK, ASK); deviation programmable from ±610 Hz to ±311.7 kHz; and crystal compensation register allows real-time correction of reference oscillator drift using 15-bit twos-complement adjustment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar UHF transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADF7021BRUZ | Integrated receiver + transmitter (transceiver); wider frequency range (30–1050 MHz); higher Rx sensitivity (−119 dBm) | Suitable for bidirectional protocols (e.g., ACK-based systems); requires additional Rx frontend design effort | Select when two-way communication or improved link budget is required; not drop-in due to different register map and pinout |
| SI4432-B1B-FM | Higher max output (+20 dBm); integrated PA matching; lower phase noise (−120 dBc/Hz @ 1 MHz offset); different SPI interface | Better suited for long-range industrial telemetry; lacks crystal compensation register and GOOK modulation | Prefer for FCC-certified long-range deployments; requires layout revision and firmware adaptation |

FAQ
What modulation schemes does the ADF7012BRUZ-RL7 support?
The ADF7012BRUZ-RL7 supports five modulation schemes: binary frequency shift keying (FSK), Gaussian frequency shift keying (GFSK), binary on-off keying (OOK), Gaussian on-off keying (GOOK), and amplitude shift keying (ASK). Each is configured via the Modulation Register (Register 2), and all operate across the full 75–1000 MHz frequency range. The ADF7012BRUZ-RL7 does not support PSK, QAM, or spread-spectrum modulation.
How is frequency accuracy maintained across temperature in the ADF7012BRUZ-RL7?
The ADF7012BRUZ-RL7 maintains frequency accuracy using its 15-bit crystal compensation register, which adjusts the output in steps of FPFD/2¹⁵ (e.g., ~305 Hz for a 10 MHz PFD). This allows software correction of initial crystal tolerance and temperature-induced drift without external TCXO. The ADF7012BRUZ-RL7 achieves <1 ppm fine-tuning resolution, verified in production test across −40°C to +85°C.
What is the minimum external component count required to operate the ADF7012BRUZ-RL7?
The ADF7012BRUZ-RL7 requires only six external components for basic operation: one 3.6864–26 MHz crystal (or TCXO), two load capacitors (for crystal), one external VCO inductor (L1–L2), one 1 μF capacitor at CREG1, and one 470 nF capacitor at CREG2. No external loop filter, PA matching network, or voltage regulator is mandatory-though matching improves output power and harmonic suppression.
Does the ADF7012BRUZ-RL7 support FCC Part 15.247 and ETSI EN 300 220 compliance out of the box?
The ADF7012BRUZ-RL7 is designed to meet FCC Part 15.247 and ETSI EN 300 220 requirements when used with appropriate external components and layout. Its 64 kbps ASK/OOK data rate limit, programmable deviation (±19.2 kHz typical), and harmonic suppression (−24 dBc second harmonic with filter) align with both standards. Final certification requires system-level testing, but the ADF7012BRUZ-RL7's architecture minimizes redesign risk.
What is the role of the MUXOUT pin on the ADF7012BRUZ-RL7?
The MUXOUT pin on the ADF7012BRUZ-RL7 is a multiplexed output that can be configured to provide PLL lock detect, regulator ready status, or low-battery voltage indicator-selected via bits in the Function Register. It eliminates the need for external monitoring ICs and enables real-time system health checks using a single GPIO. The ADF7012BRUZ-RL7 defaults to PLL lock detect after power-up.
