ADF4350BCPZ-RL

Overview

The ADF4350BCPZ-RL is a wideband synthesizer with an integrated voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. It supports fractional-N and integer-N phase-locked loop (PLL) frequency synthesis when used with an external loop filter and reference frequency. The device features a fundamental VCO output range of 2200 MHz to 4400 MHz, extendable down to 137.5 MHz via programmable divide-by-1/2/4/8/16 circuits. Operating on a 3.0 V to 3.6 V supply, it includes a 3-wire serial interface, analog/digital lock detect, and RF mute functions. The component is housed in a 32-lead LFCSP package.

Feature Summary

• Integrated VCO with fundamental output frequency ranging from 2200 MHz to 4400 MHz
• Supports both fractional-N and integer-N PLL frequency synthesis modes
• Programmable output dividers (÷1, ÷2, ÷4, ÷8, ÷16) allowing output frequencies as low as 137.5 MHz
• Low phase noise performance with typical RMS jitter less than 0.4 ps

Applications

• Wireless infrastructure systems including W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, and DECT
• Test equipment requiring precise frequency generation
• Wireless LANs and CATV equipment
• Clock generation applications

Procurement Notes

Verify the ordering suffix RL indicates reel packaging for the ADF4350BCPZ variant. Confirm the B version specifications against the Rev. B datasheet. Ensure compatibility with 1.8 V logic levels for the 3-wire serial interface. Check moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component for designs requiring a wide tuning range up to 4.4 GHz with integrated VCO capabilities. Consider the external loop filter design carefully to optimize phase noise and spurious performance. Ensure the reference input frequency meets the specified sensitivity and bias requirements. Evaluate power consumption across different output divider settings.

Part Context

The ADF4350 belongs to the ADF4350 family of wideband synthesizers. It is functionally similar to the ADF4351 but operates at a lower maximum frequency. The BC part number designation typically indicates a specific temperature grade or manufacturing revision within the Analog Devices portfolio.

Replacement Considerations

ADF4351BCPZ-RL offers a higher frequency range up to 6 GHz. ADF4355 provides microwave frequency synthesis capabilities. Verify pinout and register compatibility before substituting with other members of the ADF43xx series.
