Product Overview
The ADF4351BCPZ-RL7 is ADI’s wideband fractional/integer-N PLL frequency synthesizer with integrated VCO. Its built-in multi-band VCO covers 2200–4400 MHz, and internal dividers deliver continuous RF output from 35 MHz to 4400 MHz. Equipped with a low-noise PFD, precision charge pump and programmable reference dividers, it is configured via a 3-wire SPI interface for fast frequency hopping and fine tuning. Housed in a thermally enhanced 32-LFCSP package, it serves as low phase-noise local oscillator hardware for wireless infrastructure, microwave backhaul, test instruments and SDR systems.
Core Advantages
Extremely Wideband Frequency Coverage
Features an integrated octave-bandwidth VCO coupled with programmable hardware output dividers, allowing continuous local oscillator (LO) generation from 35 MHz to 4.4 GHz within a single layout footprint.
Industry-Leading Phase Noise Performance
Delivers exceptional spectral purity with low in-band phase noise and minimized spurious signals, improving signal-to-noise ratios (SNR) and lowering bit error rates (BER) in high-order modulation communication links.
Flexible Fractional/Integer Operational Modes
Supports both highly accurate fractional-N mode for fine resolution frequency tuning and high-purity integer-N mode for optimal phase noise performance, giving designers complete flexibility across varying application needs.
High Integration with Small Footprint
Combines a multi-band VCO, dual-modulus prescaler, charge pump, and digital dividers onto a single die, drastically reducing discrete bill-of-materials (BOM) count, minimizing stray parasitics, and accelerating time-to-market.

Frequently Asked Questions
Q1: Is your currently available stock of the ADF4351BCPZ-RL7 100% original and genuine?
A: Yes, we guarantee that all ADF4351BCPZ-RL7 frequency synthesizers in our warehouse are 100% brand-new, factory-original products directly from Analog Devices. Every batch is tracked under strict quality verification procedures and shipped inside factory-sealed ESD moisture barrier bags on original carrier reels.
Q2: What is the mechanical role of the “RL7” suffix code on this Analog Devices part number?
A: The “RL7” suffix code indicates the specific packaging format for shipping. “RL” stands for Tape and Reel, and “7” denotes a 7-inch diameter reel size. For volume manufacturing, this configuration typically holds exactly 1,500 components per reel, optimized for high-speed automated SMT assembly.
Q3: How does the ADF4351BCPZ-RL7 generate very low frequencies like 35 MHz if its fundamental VCO runs above 2.2 GHz?
A: The ADF4351BCPZ-RL7 contains an internal 3-bit binary divider block at the output of the core VCO. When a low target frequency is programmed, the chip automatically selects a fundamental VCO frequency between 2200 MHz and 4400 MHz and routes it through the internal digital output dividers (up to divide-by-64) to synthesize lower frequencies without using large external inductors.
Q4: How can our engineering team request formal CAD footprints, layout recommendations, or bulk volume quotes?
A: Please input your product criteria and project parameters into the Quick Inquiry form located on this web page. Our specialized RF application engineering desk will review your submission and reply with full data assets and target tiered pricing within 24 hours.
