ADF4378BCCZ-RL7

Overview

The ADF4378BCCZ-RL7 is a microwave wideband synthesizer featuring an integrated voltage-controlled oscillator (VCO) and a deterministic general-purpose pulse retimer. Manufactured by Analog Devices Inc., this device operates within an output frequency range of 800 MHz to 12.8 GHz. It delivers ultra-low jitter performance, specified at 18 fsRMS with an integration bandwidth of 100 Hz to 100 MHz, and achieves a wideband noise floor of −160 dBc/Hz at 12 GHz. The component utilizes a phase detector frequency up to 500 MHz and supports reference input frequencies up to 1000 MHz. It is housed in a 48-lead, 7 mm × 7 mm LGA package.

Feature Summary

• Ultra-low jitter: 18 fsRMS (100 Hz to 100 MHz) and 27 fsRMS (ADC SNR method).
• Integrated VCO generating frequencies from 800 MHz to 12.8 GHz.
• General-purpose pulse retimer for SYSREF, SYNC, and MCS applications.
• Normalized in-band phase noise floor of −239 dBc/Hz.

Applications

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

Procurement Notes

Verify the specific ordering suffix RL7 against the manufacturer's current documentation to confirm reel packaging quantities and handling requirements. Ensure that the BCCZ designation matches the required temperature range and package variant for the intended design implementation.

Selection Notes

Select this component for designs requiring deterministic delay adjustment with step sizes less than ±0.1 ps. The device supports JESD204B and JESD204C Subclass 1 synchronization when paired with appropriate ICs. Consider the 3.3 V and 5 V power supply requirements and the need for external loop filter components connected to the VTUNE pin.

Part Context

This part belongs to the ADF4378 family of microwave wideband synthesizers. The BCCZ suffix indicates the specific lead-free, RoHS-compliant 48-lead LGA package configuration. The RL7 suffix denotes the tape and reel packaging format used for automated surface-mount assembly processes.
