ADF4350BCPZ

Overview

The ADF4350BCPZ is an Analog Devices wideband fractional-N PLL frequency synthesizer with an integrated VCO, covering RF output frequencies up to 4.4 GHz. It provides a single-chip frequency source for RF and clock applications and accepts CMOS/TTL reference inputs. The device runs from a nominal 3.0 V to 3.6 V supply and supports divider/multiplier modes for flexible output scaling.

Why Choose This Part

Offers a wide RF tuning range (to 4.4 GHz) in a single chip with an integrated VCO, reducing the need for external RF VCO components. Fractional-N capability lets you synthesize fine frequency steps while maintaining a small PCB footprint and a single 3.0-3.6 V supply compatible with common 3.3 V systems. Built-in dividers/multipliers and CMOS/TTL compatible reference interface simplify integration with microcontrollers and RF front ends.

Applications

Getting Started

Start with the ADF4350 datasheet and application notes from Analog Devices to understand register programming and RF layout guidance. Analog Devices provides an evaluation board and example register settings; use the eval board when characterizing phase noise and spurious performance before committing to your PCB layout. Control is typically done from a microcontroller using the device serial programming interface; pay attention to supply decoupling, RF grounding, and matched RF traces for best performance.
