ADF4350BCPZ-RL

Product Overview

The Analog Devices Inc. ADF4350BCPZ-RL is a surface-mount RF clock and frequency synthesizer IC intended for fanout distribution and PLL-based signal generation. It combines fractional-N and integer-N synthesizer functions with a maximum frequency of 4.4GHz. The device accepts CMOS and TTL inputs and has clock outputs, with a 1:2 input-to-output ratio and both divider and multiplier functions. It uses a 32-WFQFN exposed-pad CSP package, with a 32-LFCSP-WQ (5x5) device footprint, and operates from a 3V to 3.6V supply over a -40°C to 85°C temperature range.

Key Features

• RF clock/frequency synthesizer with PLL support and fractional-N/integer-N operation.
• Maximum operating frequency of 4.4GHz.
• CMOS and TTL input compatibility with clock output and 1:2 input-to-output ratio.
• Divider and multiplier functions are available for frequency conditioning.
• Differential input and output are not supported.
• Surface-mount 32-WFQFN exposed-pad CSP package, 32-LFCSP-WQ (5x5) footprint.
• 3V to 3.6V supply and -40°C to 85°C operating temperature range.

Applications

• RF frequency synthesis in wireless transceiver front ends and signal-generation paths.
• Clock and reference distribution for multi-channel timing boards and fanout systems.
• Frequency generation in automated test equipment and instrumentation platforms.

Design & Procurement Notes

Designers should account for the 32-WFQFN exposed-pad CSP and the 32-LFCSP-WQ (5x5) footprint when creating the PCB land pattern and thermal relief. Because the device is an RF synthesizer with a 4.4GHz maximum frequency, controlled routing, supply decoupling, and ground-plane treatment are practical layout considerations. The 3V to 3.6V supply range and -40°C to 85°C operating range should be matched to the system power and ambient environment. Input compatibility with CMOS and TTL sources allows connection to logic-level signals, while the 1:2 ratio, divider/multiplier functions, and non-differential input/output configuration should be considered when defining the output mapping and signal paths.
