ADF5356BCPZ-RL7

Overview

The ADF5356BCPZ-RL7 is a microwave 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, offering an RF output frequency range from 53.125 MHz to 13,600 MHz. The device features a noise floor of −227 dBc/Hz for integer channels and −225 dBc/Hz for fractional channels, with integrated RMS jitter of 97 fs at 6 GHz. It operates on analog/digital supplies of 3.15 V to 3.45 V and charge pump/VCO supplies of 4.75 V to 5.25 V, housed in a 32-lead LFCSP package.

Feature Summary

• Wideband operation covering 53.125 MHz to 13,600 MHz with integrated VCO fundamental range of 3400 MHz to 6800 MHz.
• Ultra-low noise performance with normalized in-band phase noise floors of −227 dBc/Hz (integer) and −225 dBc/Hz (fractional).
• Pin-compatible upgrade to the ADF5355, supporting programmable divide-by-1, 2, 4, 8, 16, 32, or 64 outputs.
• High-resolution 52-bit modulus capability with Phase Frequency Detector (PFD) operation up to 125 MHz.

Applications

• Wireless infrastructure systems including LTE, W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, and DCS.
• Point-to-point and point-to-multipoint microwave communication links.
• Satellite communications and Very Small Aperture Terminal (VSAT) equipment.
• Test equipment, instrumentation, and precision clock generation circuits.

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified supply chain partners. Confirm RoHS compliance status and check for any active Product Change Notifications (PCNs) that may affect specifications or manufacturing locations prior to procurement.

Selection Notes

Select this component for applications requiring high-frequency synthesis up to 13.6 GHz with low phase noise. Ensure external loop filter design accommodates the specified PFD frequencies up to 125 MHz and reference inputs up to 600 MHz. Verify power supply decoupling meets the requirements for AVDD/DVDD (3.3 V) and VP/VVCO (5.0 V) rails.

Part Context

The ADF5356 serves as a direct pin-compatible upgrade to the ADF5355, providing enhanced performance metrics such as lower noise floors and extended frequency ranges. It belongs to the ADF5356 family of microwave wideband synthesizers designed for demanding RF applications requiring precise frequency control and stability.

Replacement Considerations

The ADF5356BCPZ is a pin-compatible alternative to the ADF5355BCPZ. Designers upgrading from the ADF5355 should verify that external circuit parameters, particularly loop filter components, are optimized for the ADF5356's specific characteristics.
