AD9518-3BCPZ

Overview

The AD9518-3BCPZ is a six-output clock generator manufactured by Analog Devices Inc., featuring an integrated voltage-controlled oscillator (VCO) with a tuning frequency range of 2.0 GHz. The device provides three pairs of LVPECL outputs, each pair sharing a programmable divider and coarse phase delay adjustment. It supports differential or single-ended reference inputs and operates within an industrial temperature range of -40°C to +85°C. The component is housed in a 64-lead LFCSP package and is designed for applications requiring low jitter and precise phase alignment.

Feature Summary

• Integrated VCO with a 2.0 GHz tuning frequency range
• Six LVPECL outputs organized in three differential pairs
• Programmable output dividers and coarse phase delay per pair
• Supports differential or single-ended reference input configurations

Applications

• Low jitter clock distribution systems
• High-speed data converter clocking
• Synchronous Ethernet and OTN networks
• Wireless baseband infrastructure

Procurement Notes

Verify the specific suffix 'BCPZ' against official Analog Devices documentation to confirm package type and lead-free status. Confirm availability through authorized distributors as supply levels fluctuate. Ensure ESD handling protocols are followed due to moisture sensitivity classification.

Selection Notes

Select this model when a 2.0 GHz internal VCO is required rather than external oscillators. Compare against AD9518 variants with different VCO frequencies (e.g., AD9518-0 at 2.8 GHz) if higher frequency operation is needed. Verify that the LVPECL output swing meets the load requirements of the downstream components.

Part Context

This part belongs to the AD9518 family of clock generators from Analog Devices. It shares architectural similarities with other members like the AD9518-0 and AD9518-1 but differs primarily in the integrated VCO frequency specification. The family is designed for high-performance timing applications requiring multiple synchronized outputs.

Replacement Considerations

Direct functional substitutes within the same family include AD9518-0, AD9518-1, AD9518-2, and AD9518-4, depending on the required VCO frequency. Ensure pin compatibility and software register configuration remain consistent when swapping between these variants.
