AD9516-4BCPZ-REEL7

Overview

The AD9516-4BCPZ-REEL7 is a 14-output clock generator featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 1.45 GHz to 1.80 GHz. It supports up to 2.4 GHz via an external VCO or VCXO. The device provides six LVPECL outputs operating up to 1.6 GHz, four LVDS outputs up to 800 MHz, and eight CMOS outputs up to 250 MHz. Key electrical parameters include a supply voltage (VS) of 3.3 V ± 5%, additive output jitter of 225 fs rms for LVPECL, and channel-to-channel skew of less than 10 ps for paired outputs. It operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Integrated on-chip VCO tunes from 1.45 GHz to 1.80 GHz; supports external VCO/VCXO up to 2.4 GHz
• Six pairs of LVPECL outputs (up to 1.6 GHz), four pairs of LVDS outputs (up to 800 MHz), and reconfigurable CMOS outputs (up to 250 MHz)
• Additive output jitter of 225 fs rms for LVPECL and 275 fs rms for LVDS
• Programmable delays and coarse phase adjustment on each output pair

Applications

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

Procurement Notes

Verify the REEL7 suffix indicates tape and reel packaging when sourcing. Confirm the specific -4 variant designation matches the 1.6 GHz internal VCO requirement. Check RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure the ordering part number corresponds exactly to the Analog Devices manufacturer identification.

Selection Notes

Select this component when subpicosecond jitter performance and multi-format output flexibility are required. The internal VCO covers 1.45 GHz to 1.80 GHz; use external VCO options if frequencies above 1.80 GHz are needed. Verify that the 64-lead LFCSP package fits the board layout constraints. Consider the serial control port interface requirements for system integration.

Part Context

This part belongs to the AD9516 family of clock generators. The -4 suffix specifically denotes the version with an integrated 1.6 GHz VCO. Other variants in the family may feature different VCO ranges or output configurations. The REEL7 suffix specifies the bulk packaging format for automated surface-mount assembly.

Replacement Considerations

Direct substitutes within the same family include AD9516-3BCPZ-REEL7, which features a 2.0 GHz internal VCO. Cross-model replacements require verification of VCO frequency ranges and output pin compatibility.
