ADF4350BCPZ-RL7

Overview

The ADF4350BCPZ-RL7 is a wideband synthesizer with an integrated voltage-controlled oscillator (VCO) manufactured by Analog Devices. It supports fractional-N and integer-N phase-locked loop (PLL) frequency synthesis, covering an output range from 137.5 MHz to 4400 MHz. The device operates on a 3.0 V to 3.6 V power supply and features a 3-wire serial interface compatible with 1.8 V logic. Key electrical specifications include a typical RMS jitter of less than 0.4 ps, programmable dual-modulus prescalers (4/5 or 8/9), and a charge pump current ranging from 0.312 mA to 5 mA. It includes analog and digital lock detect functions, RF output mute capabilities, and a switched bandwidth fast-lock mode.

Feature Summary

• Integrated VCO with fundamental output frequency range of 2200 MHz to 4400 MHz
• Fractional-N and integer-N PLL synthesizer capabilities
• Programmable divide-by-1/-2/-4/-8/-16 output stages
• Low phase noise performance with typical RMS jitter under 0.4 ps

Applications

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

Procurement Notes

Verify the -RL7 suffix indicates tape-and-reel packaging when sourcing components. Confirm that the B version specifications align with design requirements for phase noise and output power levels. Ensure proper handling precautions are taken due to the ESD sensitivity of the high-performance RF integrated circuit.

Selection Notes

Select this component for applications requiring a wide tuning range up to 4.4 GHz with low phase noise. Consider the external loop filter requirements and reference input sensitivity (0.7 AVDD V p-p). Evaluate the need for specific output divider ratios and mute functions based on system isolation requirements.

Part Context

The ADF4350BCPZ-RL7 belongs to the ADF4350 family of wideband synthesizers. It is part of Analog Devices' portfolio of wireless and RF integrated circuits designed for high-performance frequency synthesis applications in communication and test equipment sectors.
