ADF4368BCCZ

Overview

The ADF4368BCCZ is a microwave wideband synthesizer from Analog Devices Inc., featuring an integrated voltage-controlled oscillator (VCO). It operates as a high-performance integer-N and fractional-N phase-locked loop (PLL) with an output frequency range of 800 MHz to 12.8 GHz. The device supports a maximum reference input frequency of 4 GHz and utilizes a 25-bit fixed modulus combined with a 17-bit variable modulus for precise frequency resolution. Key electrical specifications include a normalized in-band phase noise floor of −239 dBc/Hz in integer mode, a typical single-ended output power of 9 dBm at 12.8 GHz, and an operating junction temperature range of −40°C to +125°C.

Feature Summary

• Integrated VCO generating frequencies from 800 MHz to 12.8 GHz without internal doublers
• Ultra-low jitter performance (< 30 fsRMS) and normalized in-band phase noise floor of −239 dBc/Hz
• Programmable 16-step output power adjustment with up to 9 dBm output at 12.8 GHz
• 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 applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Confirm RoHS compliance status directly with the supplier prior to procurement. Ensure that the required supply voltages (3.3 V and 5 V domains) are available within the specified tolerance ranges during system design.

Selection Notes

Select this component for applications requiring wide frequency coverage up to 12.8 GHz with low phase noise. Consider the 48-lead LGA package dimensions for PCB layout constraints. Evaluate the need for external loop filter components based on the desired bandwidth and charge pump current settings. Verify compatibility with the host controller's serial peripheral interface (SPI) voltage levels.

Part Context

This part belongs to the ADF4368 series of microwave wideband synthesizers. It is designed for frequency conversion applications where high spectral purity and flexible frequency planning are critical. The device integrates the VCO, PLL, and output dividers into a single chip to reduce system complexity and board space requirements compared to discrete solutions.
