ADF4371BCCZ

Overview

The ADF4371BCCZ 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) configurations when used with external components. The device generates RF output frequencies ranging from 62.5 MHz to 32,000 MHz. Key electrical specifications include a normalized phase noise floor of −234 dBc/Hz for integer channels and an integrated RMS jitter of 38 fs (1 kHz to 100 MHz). It operates with analog/digital supplies of 3.15 V to 3.45 V and a VCO supply of 4.75 V to 5.25 V.

Feature Summary

• RF output frequency range: 62.5 MHz to 32,000 MHz
• Normalized phase noise floor: −234 dBc/Hz (Integer Channel)
• Integrated RMS jitter: 38 fs (1 kHz to 100 MHz)
• Programmable divide-by-1, 2, 4, 8, 16, 32, or 64 outputs

Applications

• Wireless infrastructure (MC-GSM, 5G)
• Test equipment and instrumentation
• Clock generation
• Aerospace and defense

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and environmental compliance. Ensure that any additional characters in the part number do not indicate variations in functionality or testing standards before finalizing procurement.

Selection Notes

Select this component for applications requiring ultra-wideband frequency synthesis up to 32 GHz. Consider the 7mm × 7mm, 48-terminal LGA package constraints during PCB layout. Ensure the design accommodates the required 3.3 V and 5 V power supplies and provides adequate thermal management for the specified operating temperature range.

Part Context

The ADF4371BCCZ belongs to the ADF4371 series of microwave wideband synthesizers. It is designed to replace discrete PLL/VCO solutions, offering high integration. The BCCZ suffix typically denotes the specific lead-free, RoHS-compliant LGA package variant available from Analog Devices.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Evaluate other members of the ADF437x family or comparable wideband synthesizers based on frequency range and noise performance requirements.
