AD9518-0BCPZ

Overview

The AD9518-0BCPZ is a 6-output clock generator featuring an integrated phase-locked loop (PLL) and voltage-controlled oscillator (VCO). The on-chip VCO tunes from 2.55 GHz to 2.95 GHz, with support for external VCOs up to 2.4 GHz. It provides three pairs of LVPECL outputs operating up to 1.6 GHz, each pair sharing a programmable divider (1-to-32) and coarse phase delay. Key electrical parameters include a supply voltage (VS) of 3.3 V ± 5%, additive output jitter of 225 fs rms, and channel-to-channel skew under 10 ps for paired outputs. The device operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Integrated PLL and VCO tuning range of 2.55 GHz to 2.95 GHz
• Three pairs of LVPECL outputs with 1-to-32 dividers and coarse phase delay
• Additive output jitter of 225 fs rms and channel-to-channel skew <10 ps
• Supports differential or single-ended reference inputs up to 250 MHz

Applications

• Low jitter, low phase noise clock distribution
• 10/40/100 Gb/sec networking line cards (SONET, Synchronous Ethernet, OTU2/3/4)
• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs
• High performance wireless transceivers

Procurement Notes

Verify the specific suffix 'BCPZ' against official documentation to confirm package type and lead-free status. Confirm that the ordering code matches the exact revision required for your design. Check for any environmental compliance certifications such as RoHS if applicable to your region.

Selection Notes

Select this component when subpicosecond jitter performance is critical for data converters or high-speed interfaces. Ensure the application requires exactly six LVPECL outputs. Verify that the system can accommodate the 3.3 V supply and that the frequency planning aligns with the internal VCO range or available external VCXO options.

Part Context

The AD9518-0 belongs to the AD9518 family of clock generators. It shares functional similarities with the AD9516 and AD9517 but offers a distinct combination of outputs. For applications requiring additional outputs, crystal reference inputs, zero-delay modes, or EEPROM configuration, the AD9520 and AD9522 are alternative devices in the product line.

Replacement Considerations

The AD9516 and AD9517 are similar devices within the same family but feature different output combinations. The AD9520 and AD9522 provide more outputs and additional features like EEPROM configuration. Direct pin-to-pin replacement is not guaranteed; verify electrical compatibility and pinout differences before substitution.
