AD9516-3BCPZ-REEL7

Overview

The AD9516-3BCPZ-REEL7 is a 14-output clock generator featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 1.75 GHz to 2.25 GHz. It supports up to 2.4 GHz via an external VCO or VCXO. The device provides six LVPECL output pairs operating up to 1.6 GHz, four LVDS output pairs up to 800 MHz, and reconfigurable CMOS outputs up to 250 MHz. It operates on a single 3.3 V supply within the -40°C to +85°C temperature range.

Feature Summary

• Integrated PLL with on-chip VCO (1.75–2.25 GHz) and optional external VCO support up to 2.4 GHz
• 14 total outputs: 6 LVPECL pairs (up to 1.6 GHz), 4 LVDS pairs (up to 800 MHz), and 8 CMOS outputs (up to 250 MHz)
• Additive output jitter of 225 fs rms for LVPECL and 275 fs rms for LVDS
• Programmable delays and channel-to-channel skew paired outputs of less than 10 ps

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, and MxFE
• High-performance wireless transceivers
• ATE and high-performance instrumentation

Procurement Notes

Verify that the REEL7 suffix corresponds to tape-and-reel packaging rather than tray packaging when sourcing. Confirm the specific revision level matches design requirements, as register default values may change between revisions. Ensure ESD precautions are taken during handling due to moisture sensitivity.

Selection Notes

Select this component for designs requiring subpicosecond jitter performance and multiple differential output formats. Verify that the internal VCO frequency range covers the target application needs; otherwise, plan for an external VCO connection. Check power supply constraints, as the charge pump supply (VCP) may require up to 5 V if using an external VCO.

Part Context

This part belongs to the AD9516 family of clock generators from Analog Devices. It is specifically designed for demanding phase noise and jitter applications. The BC package designation indicates a lead-free LFCSP variant compliant with RoHS standards.

Replacement Considerations

The AD9516-4BCPZ is a related member of the AD9516 family with similar specifications. Verify pinout compatibility and register settings before substitution, as differences in VCO ranges or output configurations may exist between family members.
