AD9517-0ABCPZ-RL7

Overview

The AD9517-0ABCPZ-RL7 is a 12-output clock generator featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 2.55 GHz to 2.95 GHz. It supports up to 2.4 GHz external VCO/VCXO inputs and accepts LVPECL, LVDS, or CMOS reference signals up to 250 MHz. The device provides four LVPECL outputs operating to 1.6 GHz, two pairs of LVDS outputs to 800 MHz, and reconfigurable CMOS outputs to 250 MHz. Additive jitter is specified at 225 fs rms for LVPECL and 275 fs rms for LVDS. It operates on a single 3.3 V supply within the -40°C to +85°C industrial temperature range.

Feature Summary

• Integrated VCO tunes from 2.55 GHz to 2.95 GHz; optional external VCO/VCXO support up to 2.4 GHz
• 12 outputs: 4 LVPECL (to 1.6 GHz), 4 LVDS (to 800 MHz), and 8 CMOS (to 250 MHz)
• Additive output jitter of 225 fs rms (LVPECL) and 275 fs rms (LVDS)
• Programmable delays, automatic synchronization, and reference switchover/holdover modes

Applications

• Low jitter clock distribution for high-speed data converters
• Networking line cards (10/40/100 Gb/sec, SONET, OTU2/3/4)
• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, and MxFE transceivers
• ATE and high-performance instrumentation systems

Procurement Notes

Verify the specific suffix RL7 against current Analog Devices documentation to confirm reel packaging specifications. Confirm availability status as distribution channels may list limited stock or obsolescence notices. Ensure the LFCSP-48 package thermal requirements are met during procurement planning.

Selection Notes

Select the AD9517-0 variant specifically when the internal VCO frequency range of 2.55 GHz to 2.95 GHz is required. Compare against AD9517-1, -2, -3, and -4 variants if different VCO ranges or output configurations are needed. Verify that the 3.3 V single-supply operation meets system power constraints.

Part Context

This component belongs to the AD9517 family of low-jitter clock generators. It shares the 48-lead LFCSP package and core PLL architecture with other family members but is distinguished by its specific on-chip VCO frequency range and output driver combinations.

Replacement Considerations

Direct replacements within the same family include AD9517-1ABCPZ-RL7, AD9517-2ABCPZ-RL7, AD9517-3ABCPZ-RL7, and AD9517-4ABCPZ-RL7. These alternatives offer different internal VCO tuning ranges or output configurations while maintaining pin compatibility.
