AD9517-4ABCPZ-RL7

Overview

The AD9517-4ABCPZ-RL7 is a 12-output clock generator featuring an integrated phase-locked loop and voltage-controlled oscillator. 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. The on-chip VCO tunes from 1.45 GHz to 1.80 GHz, with support for external VCOs up to 2.4 GHz. Powered by a single 3.3 V supply, it operates within the industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated PLL and VCO tuning range of 1.45 GHz to 1.80 GHz
• 12 total 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 for LVPECL and 275 fs rms for LVDS
• Programmable coarse and fine delay adjustments for channel skew control

Applications

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

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status via official documentation. Ensure proper ESD handling protocols are followed during storage and installation due to moisture sensitivity classification.

Selection Notes

Select this model when requiring multiple output formats from a single device. Use internal VCO for compact designs or external VCXO for specific frequency stability needs. Ensure power supply decoupling meets LDO stability requirements. Verify thermal management capabilities for the LFCSP-48 package under maximum load conditions.

Part Context

This part belongs to the AD9517 family, which includes variants like the AD9517-1 and AD9517-4A. These devices share core PLL and VCO architectures but differ in output configurations and package sizes. The AD9517-4 specifically offers a balanced mix of LVPECL, LVDS, and CMOS outputs suitable for complex system synchronization.

Replacement Considerations

The AD9517-4A is a similar member of the family with identical functionality but potentially different packaging or ordering suffixes. Cross-reference pinouts and electrical specifications carefully before substitution.
