AD9517-2ABCPZ

Overview

The AD9517-2ABCPZ is a 12-output clock generator from Analog Devices, featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 2.05 GHz to 2.33 GHz. It supports external VCO/VCXO inputs up to 2.4 GHz and accepts differential or single-ended reference signals up to 250 MHz. The device provides two pairs of LVPECL outputs operating up to 1.6 GHz and two pairs of LVDS outputs up to 800 MHz, which can be reconfigured as CMOS outputs up to 250 MHz. Additive output 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 PLL and VCO with a frequency range of 2.05 GHz to 2.33 GHz
• 12 outputs: 4 LVPECL (up to 1.6 GHz), 4 LVDS (up to 800 MHz), and 8 CMOS (up to 250 MHz)
• Additive output jitter of 225 fs rms (LVPECL) and 275 fs rms (LVDS)
• Programmable coarse phase delay and fine delay adjustment per channel

Applications

• 10/40/100 Gb/sec networking line cards including SONET and Synchronous Ethernet
• 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 'ABCPZ' against the manufacturer's current ordering guide to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the design accounts for the required LFCSP-48 footprint and thermal dissipation characteristics during procurement planning.

Selection Notes

Select this component when subpicosecond jitter performance is critical for data converters or high-frequency networking applications. Choose the AD9517-2 over similar family members like the AD9516 or AD9518 based on the specific combination of LVPECL and LVDS output requirements. Ensure the system design accommodates the 48-lead LFCSP package dimensions and the necessary power supply decoupling for the internal LDO regulator.

Part Context

The AD9517-2 is part of the AD9517 family of low-jitter clock generators. It shares core architecture with the AD9516 and AD9518 but differs in package size and output configuration. This specific model provides a balanced mix of high-speed LVPECL and LVDS outputs suitable for complex multi-channel timing systems requiring precise skew control.

Replacement Considerations

The AD9516 and AD9518 are functionally similar within the same family but offer different output combinations and package sizes. Verify pin compatibility and output drive requirements before substituting. No direct cross-brand replacements are documented in the provided datasheet.
