Introduction
ADF4371BCCZ-RL7 High-Performance RF Frequency Synthesizer
Wide Frequency Range, Low Phase Noise, for Communication Systems/Radar/Test Equipment, Compact IC Design
Product Overview
The ADF4371BCCZ-RL7 from Analog Devices (ADI) is a high-performance microwave wideband frequency synthesizer with integrated voltage-controlled oscillator (VCO). Engineered for ultra-stable, low-noise frequency generation, this synthesizer delivers exceptional signal integrity across a broad 62.5 MHz to 32 GHz output range. Ideal for 5G millimeter-wave infrastructure, satellite/VSAT communication systems, phased array radar, and high-end test instruments where frequency precision and miniaturization are critical.
Core Features
- Ultra-Broad Frequency Coverage: Four distinct output bands (62.5 MHz-8 GHz, 8 GHz-16 GHz, and 16 GHz-32 GHz) eliminate need for external frequency conversion modules
- Exceptional Signal Purity: Industry-leading phase noise performance (-234 dBc/Hz FOM) with integrated RMS jitter below 40 fs
- Dual Locking Modes: ~3 ms locking time (auto-calibration) or <20 μs (bypass mode) for time-critical applications
- Programmable Output Control: Adjustable power levels and RF mute function via 3-wire serial interface
- Compact Power-Efficient Design: Operates on 3.3V analog/digital supplies with optimized power management
- High-Resolution Frequency Tuning: 39-bit fractional-N modulus enables sub-millihertz resolution
