AD9516-1BCPZ

Overview

The AD9516-1 is a 14-output clock generator featuring an integrated phase-locked loop and voltage-controlled oscillator (VCO) with a tuning range of 2.30 GHz to 2.65 GHz. It 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. The device supports external VCO/VCXO inputs up to 2.4 GHz and accepts reference frequencies up to 250 MHz. Key specifications include additive output jitter as low as 225 fs rms for LVPECL and 275 fs rms for LVDS, channel-to-channel skew under 10 ps for paired outputs, and programmable coarse and fine delays. It operates on a single 3.3 V supply within the -40°C to +85°C temperature range.

Feature Summary

• Integrated VCO tunes from 2.30 GHz to 2.65 GHz; optional external VCO/VCXO support 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: 225 fs rms (LVPECL) and 275 fs rms (LVDS); channel-to-channel skew <10 ps
• Programmable delays including coarse phase delay and fine delay adjust (Δt) on LVDS/CMOS outputs

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 MxFE transceivers
• High-performance wireless transceivers and ATE instrumentation

Procurement Notes

Verify the specific suffix 'BCPZ' against the official Analog Devices ordering guide to confirm package type and RoHS compliance status. Ensure that the required development tools, such as the AD9516-1/PCBZ evaluation board, are sourced separately if hardware validation is needed. Confirm that the serial control port interface requirements match the system design constraints.

Selection Notes

Select the AD9516-1 when an internal VCO frequency range between 2.30 GHz and 2.65 GHz is required. Choose this model over other AD9516 variants if the specific VCO tuning characteristics or divider configurations align with the target frequency plan. Verify that the 64-lead LFCSP package dimensions fit the PCB layout constraints and that the thermal resistance values meet the system's heat dissipation capabilities.

Part Context

The AD9516-1 belongs to the AD9516 family of multi-output clock generators from Analog Devices. This family includes variants with different integrated VCO ranges, such as the AD9516-0 (2.8 GHz), AD9516-3 (2.0 GHz), and AD9516-4 (1.8 GHz). All members share similar functional blocks, including the PLL, dividers, and output drivers, but differ primarily in the on-chip VCO specifications and maximum output frequencies.

Replacement Considerations

Direct replacements within the same package and functionality include other AD9516 family members like the AD9516-0, AD9516-3, or AD9516-4, provided their specific VCO tuning ranges suit the application. Cross-family alternatives may require significant redesign due to differences in pin counts, output types, or power supply requirements.
