ADF4351BCPZ-RL7

Overview

The ADF4351BCPZ-RL7 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, covering an output range of 35 MHz to 4400 MHz. The device operates on a 3.0 V to 3.6 V power supply and features a programmable divide-by-1/-2/-4/-8/-16/-32/-64 output network. Key electrical specifications include a typical integrated RMS jitter of 0.3 ps and RF output power ranging from -4 dBm to +5 dBm. It utilizes a 3-wire serial interface for register control and includes analog and digital lock detect capabilities.

Feature Summary

• Integrated VCO with fundamental output frequency from 2200 MHz to 4400 MHz
• Fractional-N and integer-N PLL synthesizer modes
• Programmable divide-by-1/-2/-4/-8/-16/-32/-64 output stages
• RF output mute function controllable via pin or software

Applications

• Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT)
• Test equipment
• Wireless LANs and CATV equipment
• Clock generation

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration required for automated assembly. Confirm that the LFCSP-32 package exposed pad connection requirements are met in the PCB layout design. Ensure compatibility with the 1.8 V logic levels specified for the serial interface inputs.

Selection Notes

Select this component when a wide tuning range up to 4.4 GHz is required without external VCOs. Consider the internal charge pump current settings and RSET resistor values for loop filter design. Evaluate the dual-modulus prescaler options (4/5 or 8/9) based on the desired PFD frequency and division ratios.

Part Context

This part belongs to the ADF4351 series of wideband synthesizers. The BCPZ designation indicates the lead-free LFCSP-32 package variant. The RL7 suffix specifies the tape and reel packaging format intended for high-volume surface mount manufacturing processes.

Replacement Considerations

Direct replacements within the same family include other ADF4351 variants with different packaging or suffixes. Verify functional equivalence regarding pinout and register maps before substituting.
