ADF4350ABCPZ-RL7

Product Overview

The ADF4350ABCPZ-RL7 from Analog Devices Inc. is an RF frequency-synthesizer IC that combines PLL and RF divider functions in a surface-mount package. The device is a PLL/VCO frequency synthesizer with a maximum frequency of 4.4GHz, making it suitable for clock and timing designs that require RF signal generation, division, or synthesis. Its CMOS input and 3V to 3.6V supply range define the basic interface and power conditions for system integration.

Key Features

• RF PLL and divider IC with a 4.4GHz maximum frequency
• CMOS input interface for reference or control signaling
• 3V to 3.6V supply voltage range
• Surface-mount 32-lead LFCSP package
• PLL/VCO frequency-synthesizer function for clock and timing designs

Applications

• RF local oscillator generation in communications transceiver designs
• Clock and reference frequency synthesis in test and measurement equipment
• RF signal generation in wireless infrastructure equipment
• Frequency division and synthesis in RF front-end subsystems

Design & Procurement Notes

Designers considering the ADF4350ABCPZ-RL7 should verify that the 3V to 3.6V supply range is compatible with the board power tree and that the CMOS input can be driven correctly by the reference or control logic. The 4.4GHz maximum frequency and RF PLL/divider architecture should be evaluated against the required output frequency plan, division ratio, and timing accuracy. Because the device uses a surface-mount 32-lead LFCSP package, PCB land pattern, soldering process, and thermal relief should be planned during layout. RF-sensitive routing, decoupling, and return paths are also important to preserve the behavior of a frequency-synthesizer IC in a mixed-signal system.
