AD9517-4ABCPZ

Overview

The AD9517-4ABCPZ is a 12-output clock generator featuring an integrated phase-locked loop and voltage-controlled oscillator. The on-chip VCO tunes from 1.45 GHz to 1.80 GHz, with support for external VCOs up to 2.4 GHz. It provides two pairs of LVPECL outputs operating up to 1.6 GHz, two pairs of LVDS outputs up to 800 MHz, and eight CMOS outputs up 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 range of 1.45 GHz to 1.80 GHz
• 12 outputs: 4 LVPECL (up to 1.6 GHz), 4 LVDS (up to 800 MHz), 8 CMOS (up to 250 MHz)
• Additive output jitter of 225 fs rms (LVPECL) and 275 fs rms (LVDS)
• Programmable dividers and coarse/fine delay adjustments per channel

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 component authenticity through authorized Analog Devices distributors or direct channels. Confirm RoHS compliance status via official documentation. Ensure proper ESD handling during storage and installation due to moisture sensitivity classification. Validate package integrity upon receipt to ensure pin alignment for the 48-lead LFCSP form factor.

Selection Notes

Select this model when subpicosecond jitter performance is required for data converters or high-speed interfaces. Choose based on specific output interface needs: LVPECL for high-frequency distribution, LVDS for medium frequency with fine delay control, or CMOS for lower frequency logic interfacing. Consider the internal VCO range versus external VCXO requirements for frequency synthesis flexibility.

Part Context

This component belongs to the AD9517 family of clock generators. It differs from the AD9516 and AD9518 primarily in package size and the number/configuration of available outputs. The AD9517-4 specifically offers the combination of LVPECL, LVDS, and CMOS outputs detailed in its specifications.

Replacement Considerations

The AD9516 and AD9518 are similar devices within the same family but differ in package dimensions and output counts. Verify pin compatibility and output configuration requirements before substituting.
