AD9516-2BCPZ

Overview

The AD9516-2BCPZ is a 14-output clock generator featuring an integrated phase-locked loop and voltage-controlled oscillator (VCO). The on-chip VCO tunes from 2.05 GHz to 2.33 GHz, with support for external VCOs up to 2.4 GHz. It provides six LVPECL outputs operating to 1.6 GHz, four LVDS outputs to 800 MHz, and eight CMOS outputs to 250 MHz. Additive output jitter is specified at 225 fs rms for LVPECL and 275 fs rms for LVDS. The device operates on a single 3.3 V supply within the -40°C to +85°C industrial temperature range.

Feature Summary

• Integrated PLL and VCO tuning range of 2.05 GHz to 2.33 GHz
• Six pairs of LVPECL outputs (up to 1.6 GHz) with <10 ps channel-to-channel skew
• Four pairs of LVDS outputs (up to 800 MHz) with fine delay adjustment
• Eight CMOS outputs derived from LVDS channels (up to 250 MHz)
• Additive output jitter of 225 fs rms (LVPECL) and 275 fs rms (LVDS)

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, and MxFEs
• High performance wireless transceivers

Procurement Notes

Verify the specific suffix BCPZ corresponds to the LFCSP-64 package and industrial temperature grade (-40°C to +85°C). Confirm that the ordering information matches the Rev. C datasheet specifications. Ensure compatibility with the required power supply voltages and reference input formats before procurement.

Selection Notes

Select the AD9516-2BCPZ when an internal VCO frequency between 2.05 GHz and 2.33 GHz is required. Choose this model over other AD9516 variants if the specific VCO tuning range aligns with the system's frequency planning needs. Verify that the 14-output configuration meets the distribution requirements for the target application.

Part Context

The AD9516-2 is part of the Analog Devices AD9516 family of multi-output clock generators. It shares the same pinout and functional architecture as other members like the AD9516-0 and AD9516-3 but differs in the integrated VCO tuning range. This specific variant is optimized for applications requiring the 2.05 GHz to 2.33 GHz internal oscillation band.

Replacement Considerations

Direct replacements within the AD9516 family include the AD9516-0BCPZ (VCO: 2.55–2.95 GHz), AD9516-3BCPZ (VCO: ~2.0 GHz), and AD9516-4BCPZ (VCO: 1.6 GHz). Selection depends on matching the required internal VCO frequency range for the specific design.
