ADF4356BCPZ-RL7

Overview

The ADF4356BCPZ-RL7 is a wideband frequency synthesizer featuring an integrated voltage-controlled oscillator (VCO) with a fundamental range of 3400 MHz to 6800 MHz. It supports RF output frequencies from 53.125 MHz to 6800 MHz via programmable dividers. The device implements fractional-N and integer-N synthesis architectures, achieving normalized in-band phase noise floors of −225 dBc/Hz for fractional channels and −227 dBc/Hz for integer channels. Integrated RMS jitter is specified at 97 fs between 1 kHz and 20 MHz offsets at a 6 GHz output. Power supplies include 3.3 V for analog/digital sections and 5.0 V typical for the charge pump and VCO.

Procurement Notes

Verify component authenticity through authorized Analog Devices distribution channels. Confirm package integrity for the LFCSP-32 form factor upon receipt. Ensure handling procedures adhere to ESD protection standards, as the device is sensitive to electrostatic discharge. Cross-reference ordering information with official manufacturer documentation to validate specific suffix designations.

Selection Notes

Select this component for applications requiring wideband frequency synthesis up to 6.8 GHz with low phase noise characteristics. Ensure external loop filter components are compatible with the internal charge pump current settings. Verify that system power supply rails match the specified 3.3 V and 5.0 V requirements. Consider PCB thermal design guidelines due to the chip-scale package configuration to maintain optimal performance within the operating temperature range.

Part Context

This part belongs to the ADF4356 series of wideband synthesizers manufactured by Analog Devices Inc. It serves as a direct pin-compatible replacement for the ADF4355, offering enhanced performance specifications while maintaining mechanical compatibility for existing designs. The device integrates both fractional-N and integer-N PLL functionalities into a single compact solution.

Replacement Considerations

The ADF4356BCPZ-RL7 is explicitly documented as a pin-compatible upgrade for the ADF4355. Designers migrating from the ADF4355 should verify register configurations and external component values to accommodate the updated electrical characteristics of the newer device.
