AD9517-2ABCPZ-RL7

Overview

The AD9517-2ABCPZ-RL7 is a 12-output clock generator featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 2.05 GHz to 2.33 GHz. It supports up to 2.4 GHz using an external VCO or VCXO. The device provides four LVPECL outputs operating up to 1.6 GHz, four LVDS outputs up to 800 MHz, and eight CMOS outputs up to 250 MHz. It operates on a single 3.3 V supply within the industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated VCO tunes from 2.05 GHz to 2.33 GHz; supports external VCO/VCXO up to 2.4 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
• Automatic holdover and flexible reference input circuitry for smooth switching

Applications

• Low jitter, low phase noise clock distribution
• 10/40/100 Gb/sec networking line cards including SONET, Synchronous Ethernet, OTU2/3/4
• Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs
• High performance wireless transceivers
• ATE and high performance instrumentation

Procurement Notes

Verify the specific suffix RL7 against official documentation to confirm reel packaging specifications. Confirm that the AB designation aligns with the required temperature and electrical parameters. Cross-reference the package type LFCSP-48 with board layout requirements. Ensure compatibility with the intended power supply voltages and reference input formats before procurement.

Selection Notes

Select this component when subpicosecond jitter performance and multi-format output flexibility are required. The internal VCO covers 2.05 GHz to 2.33 GHz, suitable for direct synthesis or frequency multiplication. Consider the AD9516 or AD9518 if different output combinations or package sizes are needed. Verify that the serial control port interface matches the system's microcontroller capabilities.

Part Context

The AD9517-2 is part of the AD9517 family of clock generators. It differs from the AD9516 and AD9518 primarily in package size and the number of available outputs. The AD9517-2 specifically offers a balanced mix of LVPECL, LVDS, and CMOS outputs in a 48-lead LFCSP package, targeting high-performance data converter and networking applications.

Replacement Considerations

The AD9516 and AD9518 are functionally similar members of the same family but differ in package dimensions and output counts. Direct substitution requires verifying pinout compatibility and ensuring the alternative package fits the existing footprint.
