AD9517-3ABCPZ

Overview

The AD9517-3ABCPZ is a 12-output clock generator from Analog Devices, featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 1.75 GHz to 2.25 GHz. It supports external VCOs up to 2.4 GHz and operates on a single 3.3 V supply. The device provides two pairs of LVPECL outputs (up to 1.6 GHz), two pairs of LVDS outputs (up to 800 MHz), and reconfigurable CMOS outputs (up to 250 MHz). Key electrical parameters include additive output jitter of 225 fs rms for LVPECL and 275 fs rms for LVDS. It is housed in a 48-lead LFCSP package and rated for industrial temperatures from -40°C to +85°C.

Feature Summary

• Integrated PLL and VCO with a frequency range of 1.75 GHz to 2.25 GHz
• Four LVPECL outputs operating up to 1.6 GHz with <10 ps channel-to-channel skew
• Four LVDS outputs operating up to 800 MHz with fine delay adjustment
• Reconfigurable LVDS outputs as eight CMOS outputs up to 250 MHz

Applications

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

Procurement Notes

Verify the specific suffix AB against official documentation to confirm package type and temperature grade. Ensure the ordering code matches the exact Rev F specifications. Confirm RoHS compliance status through the manufacturer's current datasheet revision before procurement.

Selection Notes

Select this component when subpicosecond jitter performance is critical for data converters or high-speed interfaces. Choose the internal VCO for compact designs or an external VCXO if precise frequency control up to 2.4 GHz is required. Verify that the 3.3 V single-supply operation meets system power constraints.

Part Context

The AD9517-3 is part of the AD9517 family, which includes variants like the AD9516 and AD9518. These devices share similar core architectures but differ in output combinations and VCO frequencies. The AD9517-3 specifically targets applications requiring a balance of LVPECL and LVDS outputs with an integrated 2.0 GHz class VCO.

Replacement Considerations

The AD9517-0A/PCBZ is an evaluation board for the AD9517-0 variant, which features a 2.8 GHz VCO. Direct pin-compatible replacements within the same family include the AD9517-3ABCPZ itself or other suffixes of the AD9517 series, provided the VCO frequency range and output configurations match the design requirements.
