ADF4350ABCPZ

Product Overview

The ADF4350ABCPZ from Analog Devices Inc. is a surface-mount RF frequency synthesizer IC with PLL, VCO, and a 32LFCSP package. Its technical specifications identify it as a PLL and RF divider device with a CMOS input and a maximum frequency of 4.4 GHz. The supply voltage range is 3 V to 3.6 V, defining the operating envelope for board-level power distribution and input logic interfacing. As a clock and timing integrated circuit, it is intended for RF signal generation and frequency synthesis tasks where a phase-locked loop architecture and RF divider function are central to the circuit design. The 32LFCSP surface-mount form factor supports compact RF subsystem layouts, while the CMOS input requires attention to compatible control signal levels and timing during system integration.

Key Features

• PLL and RF divider function for frequency synthesis applications.
• CMOS input for control and interface considerations.
• Maximum operating frequency of 4.4 GHz.
• Supply voltage range of 3 V to 3.6 V.
• 32LFCSP surface-mount package for compact RF board layouts.
• PLL synthesizer architecture with VCO.

Applications

• RF local oscillator generation in transceiver front-end circuits.
• Frequency synthesis in RF test and measurement equipment.
• Clock and timing generation within RF subsystems.

Design & Procurement Notes

Designers should verify that the 3 V to 3.6 V supply range, CMOS input characteristics, and 32LFCSP surface-mount package fit the target board and control logic. The 4.4 GHz maximum frequency and RF PLL/divider architecture call for careful layout, impedance control, and supply decoupling during schematic and PCB development. Procurement should reference the exact manufacturer part number ADF4350ABCPZ from Analog Devices Inc. to ensure the selected component matches the intended RF frequency synthesis function. Because the device is a surface-mount IC, assembly process compatibility and pad geometry should be reviewed early in the design cycle.
