ADF4368BCCZ-RL7

Overview

The ADF4368BCCZ-RL7 is a microwave wideband synthesizer with an integrated VCO, designed for frequency conversion applications. It operates as an integer-N and fractional-N phase-locked loop (PLL) generating output frequencies from 800 MHz to 12.8 GHz without internal doublers. Key electrical specifications include a normalized in-band phase noise floor of −239 dBc/Hz in integer mode and −237 dBc/Hz in fractional mode. The device supports a maximum reference input frequency of 4 GHz and achieves ultra-low jitter, typically less than 30 fsRMS at 9.001 GHz. It features a 25-bit fixed modulus and a 49-bit combined fractional modulus for precise frequency resolution.

Feature Summary

• Integrated VCO generates frequencies from 800 MHz to 12.8 GHz without sub-harmonic filters
• Ultra-low jitter performance (< 30 fsRMS) and normalized 1/f phase noise floor of −287 dBc/Hz
• Programmable output power up to 9 dBm at 12.8 GHz with 16-step adjustment
• Multichip synchronization via SYNC pin or EZSync method for phase alignment

Applications

• Wireless infrastructure including MC-GSM and 5G systems
• Test and measurement equipment
• Aerospace and defense radar systems

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration required for production integration. Confirm that the LGA-48 package thermal requirements are met by the PCB design, specifically regarding the exposed paddle connection to ground for optimal thermal dissipation and signal integrity.

Selection Notes

Select this component when high-frequency synthesis up to 12.8 GHz is required without external multiplier stages. Ensure the application can accommodate the dual supply voltage architecture, utilizing 3.15 V to 3.45 V for logic and 4.75 V to 5.25 V for analog sections. Consider the simplified SPI interface and ADIsimPLL support for rapid loop filter design and system integration.
