AD9518-3BCPZ-REEL7

Overview

The AD9518-3BCPZ-REEL7 is a high-performance clock generator and fanout distribution IC manufactured by Analog Devices Inc. It features an integrated 2.0 GHz voltage-controlled oscillator (VCO) and provides six output channels. The device supports differential input and output configurations, including LVPECL and CMOS options, with a maximum operating frequency of 2.95 GHz. Packaged in a 48-lead LFCSP, it operates within a temperature range of -40°C to +85°C and requires a supply voltage between 3.135 V and 3.465 V.

Feature Summary

• Integrated 2.0 GHz VCO for standalone clock generation
• Six differential output channels supporting LVPECL and CMOS
• Maximum output frequency up to 2.95 GHz
• Low skew clock distribution with programmable delays

Applications

• High-speed data converter clocking systems
• Telecommunications infrastructure timing
• Test and measurement equipment synchronization
• Aerospace and defense radar systems

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Check for moisture sensitivity level (MSL) requirements during storage and handling to prevent package damage. Ensure the supplier provides traceability certificates if required for aerospace or medical applications.

Selection Notes

Select this component when a single-chip solution combining a PLL synthesizer and fanout buffer is required. Compare against other AD9518 variants based on the integrated VCO frequency; the -3 suffix specifies a 2.0 GHz VCO. Verify that the 48-pin LFCSP package fits the PCB footprint constraints. Ensure the application supports the 3.3 V nominal supply voltage and differential signaling standards.

Part Context

This part belongs to the AD9518 family of clock generators from Analog Devices. The base model AD9518 offers multiple VCO options, with the -3 variant specifically integrating a 2.0 GHz VCO. It is designed for applications requiring low phase noise and precise jitter performance. Evaluation boards such as the AD9518-0A-PCBZ are available for development and testing purposes.

Replacement Considerations

Direct substitutes include other AD9518 variants with different VCO frequencies (e.g., AD9518-0, AD9518-1, AD9518-2, AD9518-4) if the VCO frequency matches system requirements. Cross-reference pinouts and electrical specifications before replacing to ensure compatibility with existing circuit designs.
