AD9517-3ABCPZ-RL7

Overview

The AD9517-3ABCPZ-RL7 is a 12-output clock generator featuring an integrated phase-locked loop and voltage-controlled oscillator (VCO). The on-chip VCO operates within a frequency range of 1.75 GHz to 2.25 GHz, with support for external VCOs up to 2.4 GHz. It provides four LVPECL outputs capable of frequencies up to 1.6 GHz, two pairs of LVDS outputs operating up to 800 MHz, and reconfigurable CMOS outputs up to 250 MHz. The device accepts differential or single-ended reference inputs up to 250 MHz and functions on a single 3.3 V supply across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated PLL and VCO tuning from 1.75 GHz to 2.25 GHz
• Four LVPECL outputs (up to 1.6 GHz) and four LVDS outputs (up to 800 MHz)
• LVDS outputs reconfigurable as eight CMOS outputs (up to 250 MHz)
• Programmable delays and coarse phase adjustment for all output channels

Applications

• Low jitter clock distribution for networking line cards
• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, and MxFEs
• High-performance wireless transceivers
• ATE and high-performance instrumentation

Procurement Notes

Verify the specific suffix RL7 against the manufacturer's current ordering guide to confirm reel packaging specifications. Confirm RoHS compliance status through official documentation prior to integration. Ensure ESD handling protocols are followed due to the moisture sensitivity classification associated with the LFCSP package type.

Selection Notes

Select this component when subpicosecond jitter performance and low phase noise are critical for data converter applications. Choose the AD9517-3 over other family members if the specific combination of LVPECL and LVDS/CMOS outputs is required. Verify that the system power supply can accommodate the nominal 3.3 V operation and potential 5 V requirement for external VCO charge pump supplies.

Part Context

This part belongs to the AD9517 family of multi-output clock generators from Analog Devices. It shares architectural similarities with the AD9516 and AD9518 but offers a distinct output configuration optimized for demanding phase noise requirements. The device is designed to maximize data converter performance through precise clock distribution and synchronization capabilities.

Replacement Considerations

The AD9517-1 and AD9517-4 are alternative members of the same family. Selection should be based on verifying output count and frequency specifications against the original design requirements.
