AD9516-0BCPZ

Overview

The AD9516-0BCPZ is a 14-output clock generator featuring an integrated phase-locked loop and voltage-controlled oscillator (VCO). The on-chip VCO tunes from 2.55 GHz to 2.95 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 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 from 2.55 GHz to 2.95 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 including SONET and OTU2/3/4
• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, and MxFEs
• High performance wireless transceivers
• ATE and high performance instrumentation

Procurement Notes

Verify the specific suffix BCPZ corresponds to the lead-free LFCSP-64 package configuration. Confirm that the ordering code matches the Rev. C datasheet specifications for the AD9516-0 variant. Ensure compatibility with the required 3.3 V power supply and thermal management requirements for the exposed paddle ground connection.

Selection Notes

Select this model when an integrated VCO covering 2.55 GHz to 2.95 GHz is required. Choose over other AD9516 variants if the higher frequency range is necessary, as other models may feature lower frequency VCOs. Verify that the 14-output count and mixed interface types (LVPECL, LVDS, CMOS) align with the system design constraints.

Part Context

The AD9516-0 belongs to the Analog Devices AD9516 family of multi-output clock generators. It shares the same functional architecture and pinout with other members like the AD9516-3 and AD9516-4, differentiated primarily by the internal VCO tuning range. The BC designation indicates the commercial temperature grade and lead-free packaging.

Replacement Considerations

Direct replacements within the family include the AD9516-3BCPZ and AD9516-4BCPZ, provided the application can accommodate their respective lower VCO frequency ranges. Cross-family alternatives such as the AD9517 or AD9518 series offer different output counts and pinouts, requiring schematic redesign.
