AD9516-3BCPZ

Overview

The AD9516-3BCPZ is a 14-output clock generator featuring an integrated phase-locked loop and a voltage-controlled oscillator (VCO) that tunes from 1.75 GHz to 2.25 GHz. It supports up to 2.4 GHz external VCOs and accepts LVPECL, LVDS, or CMOS references up to 250 MHz. The device provides six pairs of LVPECL outputs operating to 1.6 GHz with 225 fs rms additive jitter, and four pairs of LVDS outputs operating to 800 MHz with 275 fs rms additive jitter. Each LVDS output can be reconfigured as two 250 MHz CMOS outputs. Packaged in a 64-lead LFCSP, it operates on a single 3.3 V supply across the -40°C to +85°C temperature range.

Feature Summary

• Integrated PLL with on-chip VCO tuning range of 1.75 GHz to 2.25 GHz
• Six pairs of LVPECL outputs (up to 1.6 GHz) and four pairs of LVDS outputs (up to 800 MHz)
• LVDS outputs configurable as dual 250 MHz CMOS outputs
• Programmable delays and coarse phase adjustment for all output channels

Applications

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

Procurement Notes

Verify the specific suffix 'BCPZ' corresponds to the tray-packaged 64-lead LFCSP variant. Confirm the internal VCO frequency range matches the design requirement of 1.75 GHz to 2.25 GHz, as other family members may differ. Ensure the serial control port interface and register map are compatible with the system controller.

Selection Notes

Select this component when subpicosecond jitter performance is critical for data converter applications. The AD9516-3 is distinct within the AD9516 family due to its specific 2.0 GHz VCO range. Verify that the required number of LVPECL and LVDS/CMOS outputs aligns with the 14-output configuration provided by this specific part number.

Part Context

The AD9516-3BCPZ belongs to the Analog Devices AD9516 family of multi-output clock generators. It shares the same package and general architecture with variants like the AD9516-0 and AD9516-4 but is differentiated by its internal VCO tuning range. The BC designation indicates the industrial temperature grade (-40°C to +85°C).

Replacement Considerations

Direct replacements within the AD9516 family include the AD9516-0BCPZ (2.8 GHz VCO), AD9516-4BCPZ (1.8 GHz VCO), and AD9516-2BCPZ. These parts share the same pinout and register map but require verification of the VCO frequency range against the application's clock generation needs.
