AD9518-0ABCPZ-RL7

Overview

The AD9518-0ABCPZ-RL7 is a six-output clock generator featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 2.55 GHz to 2.95 GHz. It supports external VCO or VCXO inputs up to 2.4 GHz and accepts LVPECL, LVDS, or CMOS reference signals up to 250 MHz. The device provides three pairs of LVPECL outputs operating at frequencies up to 1.6 GHz, each equipped with programmable dividers ranging from 1 to 32 and coarse phase delay capabilities. Key performance metrics include an additive output jitter of 225 fs rms and channel-to-channel skew of less than 10 ps for paired outputs. It operates on a single 3.3 V supply within the industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated VCO tunes from 2.55 GHz to 2.95 GHz; supports external VCO/VCXO up to 2.4 GHz
• Six LVPECL outputs in three pairs, supporting frequencies up to 1.6 GHz with 1-to-32 division ratios
• Additive output jitter of 225 fs rms and channel-to-channel skew under 10 ps
• Programmable delays, automatic/manual synchronization, and reference monitoring

Applications

• Low jitter, low phase noise clock distribution systems
• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, and MxFE devices
• 10/40/100 Gb/sec networking line cards including SONET, Synchronous Ethernet, and OTU2/3/4
• High-performance wireless transceivers and ATE instrumentation

Procurement Notes

Verify the RL7 suffix indicates reel packaging when sourcing this component. Confirm that the specific revision matches the required datasheet specifications. Ensure compatibility with the 48-lead LFCSP footprint during procurement planning.

Selection Notes

Select the AD9518-0ABCPZ-RL7 for applications requiring subpicosecond jitter performance and multiple LVPECL outputs. Consider the internal VCO range of 2.55 GHz to 2.95 GHz or external input limits of 2.4 GHz based on system requirements. Evaluate power supply constraints, as the charge pump supply may require connection to 5 V for external VCO operation.

Part Context

This component belongs to the AD9518 family of clock generators. Other members such as the AD9516 and AD9517 share similar functionality but differ in package size and the number of available outputs. The AD9518-0 specifically provides six LVPECL outputs in a 48-lead LFCSP package.

Replacement Considerations

The AD9518-0ABCPZ is the tray-packaged equivalent of this part. For higher output counts, the AD9520 and AD9522 are available alternatives.
