ADF4377BCCZ-U3

Overview

The ADF4377BCCZ-U3 is a high-performance, ultralow jitter, dual-output integer-N phase-locked loop (PLL) featuring an integrated voltage-controlled oscillator (VCO). Manufactured by Analog Devices Inc., this component operates within an output frequency range of 800 MHz to 12.8 GHz. It is designed for data converter and mixed-signal front-end clock applications, offering a figure of merit of -239 dBc/Hz and ultralow 1/f noise. The device supports automatic reference-to-output synchronization and includes matched delays across process, voltage, and temperature variations.

Feature Summary

• Integrates a wideband VCO generating frequencies from 800 MHz to 12.8 GHz with dual outputs.
• Provides ultralow jitter performance suitable for demanding data converter and MxFE clock applications.
• Includes automatic reference-to-output synchronization and precise delay adjustment capabilities.

Applications

• Data converter clock generation
• Mixed-signal front-end (MxFE) clocking
• JESD204B and JESD204C Subclass 1 system synchronization

Procurement Notes

Verify the specific suffix 'U3' against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with standard LGA-48 footprints if applicable. Confirm RoHS compliance status through current datasheets before procurement.

Selection Notes

Select this component when ultralow jitter and wideband synthesis are required for high-speed data converters. Consider its integrated VCO and synchronization features for simplifying multi-chip clock alignment in complex mixed-signal systems requiring precise SYSREF distribution.

Part Context

This part belongs to the ADF4377 series of microwave wideband synthesizers. It shares core PLL and VCO architecture with variants like the ADF4377BCCZ-RL7 but may differ in packaging or reel configuration. It serves as a specialized solution for high-frequency clocking needs in advanced communication and signal processing equipment.

Replacement Considerations

Direct substitutes include other ADF4377 variants such as ADF4377BCCZ-RL7. Verify functional equivalence regarding output frequency ranges and jitter specifications before substitution.
