ADF4377BCCZ

Overview

The ADF4377BCCZ-RL7 is a high-performance, ultralow jitter, dual-output integer-N phase-locked loop (PLL) with an integrated voltage-controlled oscillator (VCO). Designed for data converter and mixed-signal front-end clocking applications, it generates output frequencies from 800 MHz to 12.8 GHz. The device features a figure of merit of −239 dBc/Hz, normalized in-band 1/f noise of −147 dBc/Hz, and wideband noise floor of −160 dBc/Hz at 12 GHz. It achieves integrated jitter of 18 fs RMS (100 Hz to 100 MHz) and supports reference input frequencies up to 1000 MHz with a phase detector frequency up to 500 MHz.

Feature Summary

• Dual differential outputs with programmable amplitude and divider settings
• Integrated VCO generating 800 MHz to 12.8 GHz with ultralow jitter
• Automatic reference-to-output synchronization for multichip alignment
• Sub-picosecond delay adjustment capability (< ±0.1 ps step size)

Applications

• High-performance data converter and MxFE clocking
• Wireless infrastructure including MC-GSM and 5G systems
• Test and measurement equipment

Procurement Notes

Verify the specific ordering suffix RL7 indicates reel packaging when sourcing components. Confirm that the LGA-48 package variant matches the required footprint for the target PCB design. Ensure supply chain documentation aligns with Analog Devices Inc. manufacturing standards for this microwave synthesizer series.

Selection Notes

Select the ADF4377BCCZ-RL7 for applications requiring precise multichip clock and SYSREF alignment. The device supports JESD204B and JESD204C Subclass 1 solutions when paired with appropriate distribution ICs. Consider the integrated bypass capacitors for board space savings and the wide operating temperature range from -40°C to +105°C.

Part Context

The ADF4377 belongs to the Analog Devices ADF437x family of microwave wideband synthesizers. It complements other devices like the ADF4371 and ADF4372 by offering optimized performance for data converter clocking with lower jitter and advanced synchronization features. The BCCZ designation identifies the specific lead-free LGA-48 package configuration.
