ADF4372BCCZ

Overview

The ADF4372BCCZ 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, generating output frequencies from 62.5 MHz to 16 GHz. The device features a 39-bit fractional modulus for high resolution and 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. Key performance metrics include a normalized in-band phase noise floor of −234 dBc/Hz and integrated RMS jitter of 38 fs (1 kHz to 100 MHz). It utilizes a 3-wire serial interface for register control and is housed in a 7 mm × 7 mm, 48-terminal LGA package.

Feature Summary

• RF output frequency range: 62.5 MHz to 16,000 MHz
• Integrated VCO with fundamental range of 4000 MHz to 8000 MHz
• Normalized in-band phase noise floor: −234 dBc/Hz (integer channel)
• Programmable divide-by-1, 2, 4, 8, 16, 32, or 64 outputs

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and temperature grade. Confirm availability status as distribution channels may report limited stock or restricted supply conditions. Ensure the external loop filter components are selected to meet the specified lock time and phase noise requirements.

Selection Notes

Select the appropriate RF output port (RF8x, RFAUX8x, or RF16x) based on the required frequency range, noting that RF16x provides 8 GHz to 16 GHz via a doubler. Choose between 3.3 V or 5 V VCO supply configurations depending on the desired phase noise performance and output power levels. Ensure the reference input configuration matches the available clock source, supporting single-ended up to 500 MHz or differential up to 600 MHz.

Part Context

The ADF4372 belongs to the ADF437x family of microwave wideband synthesizers from Analog Devices. It is designed for applications requiring high-frequency coverage and low phase noise. The BCCZ suffix indicates a specific lead-free, RoHS-compliant variant in the 48-terminal LGA package. It serves as a direct replacement for previous generations in systems requiring 16 GHz synthesis capabilities.
