AD9516-0BCPZ-REEL7

Overview

The AD9516-0BCPZ-REEL7 is a 14-output clock generator featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 2.55 GHz to 2.95 GHz. It supports up to 2.4 GHz external VCO/VCXO inputs and accepts LVPECL, LVDS, or CMOS references up to 250 MHz. The device provides six pairs of LVPECL outputs operating to 1.6 GHz, four pairs of LVDS outputs to 800 MHz, and reconfigurable CMOS outputs to 250 MHz. Additive output jitter is specified at 225 fs rms for LVPECL and 275 fs rms for LVDS. It operates on a single 3.3 V supply within the -40°C to +85°C temperature range.

Feature Summary

• Integrated VCO tunes from 2.55 GHz to 2.95 GHz; optional external VCO/VCXO support up to 2.4 GHz
• 14 outputs: 6 pairs of LVPECL (to 1.6 GHz), 4 pairs of LVDS (to 800 MHz), and reconfigurable CMOS (to 250 MHz)

Procurement Notes

Verify the REEL7 suffix indicates tape and reel packaging when sourcing. Confirm the specific AD9516-0 variant matches the required internal VCO frequency range of 2.55 GHz to 2.95 GHz. Ensure compatibility with the 64-lead LFCSP package dimensions and moisture sensitivity level requirements during assembly.

Selection Notes

Select this component for applications requiring subpicosecond jitter performance and multiple differential output formats. The AD9516-0 is distinct from other family members by its specific internal VCO tuning range. Consider the programmable divider ratios and fine delay adjustments available for each output pair when designing complex clock trees.

Part Context

The AD9516-0 belongs to the Analog Devices AD9516 family of multi-output clock generators. This specific model integrates a high-frequency VCO optimized for low phase noise. Other variants in the series may feature different VCO ranges or external VCO dependencies, making the -0 suffix critical for identifying the correct internal oscillator specifications.

Replacement Considerations

Direct substitutes include other AD9516 family members such as AD9516-1, AD9516-2, AD9516-3, and AD9516-4. Verify that the alternative variant's internal VCO frequency range and output configurations match the design requirements before substitution.
