ADF4350BCPZ-RL7

Product Overview

The ADF4350BCPZ-RL7 from Analog Devices Inc. is a surface-mount RF clock/frequency synthesizer and fanout distribution device intended for timing and signal-generation functions in electronic assemblies. It combines fractional-N and integer-N PLL operation with divider and multiplier capabilities, allowing a single circuit to process and distribute clock signals. The device accepts CMOS and TTL inputs, provides a clock output, and is rated for a maximum frequency of 4.4 GHz. It operates from a 3 V to 3.6 V supply across a -40°C to 85°C temperature range. The package is a 32-WFQFN exposed-pad CSP, identified as 32-LFCSP-WQ (5x5).

Key Features

• Analog Devices ADF4350BCPZ-RL7 is a surface-mount RF clock/frequency synthesizer and fanout distribution device.
• Supports fractional-N and integer-N PLL operation with divider and multiplier functions.
• Accepts CMOS and TTL inputs and provides a clock output.
• Rated for a maximum frequency of 4.4 GHz.
• Operates from a 3 V to 3.6 V supply over -40°C to 85°C.
• Uses a single circuit with a 1:2 input-to-output ratio and non-differential input/output configuration.
• Housed in a 32-WFQFN exposed-pad CSP package, 32-LFCSP-WQ (5x5).

Applications

• Clock and RF frequency synthesis for communications hardware.
• Board-level fanout distribution of a common clock or timing signal.
• Frequency generation in RF measurement and instrumentation systems.
• Reference signal generation for RF transceiver and receiver designs.

Design & Procurement Notes

Design and procurement review should confirm that the board power rail remains within the 3 V to 3.6 V supply range and that the operating environment stays within -40°C to 85°C. The 1:2 input-to-output ratio, single-circuit architecture, and non-differential input/output configuration should be checked against the required fanout and interface style. Because the device accepts CMOS and TTL inputs and provides a clock output, input compatibility and output loading should be verified during schematic and layout planning. The 32-WFQFN exposed-pad CSP package requires a surface-mount land pattern that accommodates the exposed pad and the 32-LFCSP-WQ (5x5) package.
