AD9517-1ABCPZ

Overview

The AD9517-1ABCPZ is a 12-output clock generator from Analog Devices, housed in a 48-lead LFCSP package. It integrates a phase-locked loop (PLL) and a voltage-controlled oscillator (VCO) with a tuning range of 2.30 GHz to 2.65 GHz. The device supports up to 2.4 GHz external VCO/VCXO inputs. Output configurations include two pairs of LVPECL outputs operating up to 1.6 GHz, two pairs of LVDS outputs up to 800 MHz, and reconfigurable CMOS outputs up to 250 MHz. It operates on a single 3.3 V supply within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated PLL and VCO with a frequency range of 2.30 GHz to 2.65 GHz
• 12 outputs: 4 LVPECL (up to 1.6 GHz), 4 LVDS (up to 800 MHz), and 8 CMOS (up to 250 MHz)
• Low additive output jitter: 225 fs rms for LVPECL and 275 fs rms for LVDS
• Supports differential or dual single-ended reference inputs up to 250 MHz

Applications

• Low jitter, low phase noise clock distribution
• 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

Procurement Notes

Verify the specific suffix AB against official documentation to confirm package type and temperature grade. Confirm availability status as supply conditions may vary. Ensure the ordering code matches the required Rev F specifications for electrical parameters.

Selection Notes

Select this component when subpicosecond jitter performance is critical for data converter applications. Choose the internal VCO configuration for compact designs or use the external VCO input if frequencies above 2.65 GHz are not required but specific tuning ranges are needed. Verify power supply requirements for VS_LVPECL if separate termination voltages are utilized.

Part Context

This part belongs to the AD9517 family of multi-output clock generators. Other variants such as the AD9517-4 offer different VCO ranges and output combinations. The AD9517-1 specifically targets high-frequency applications requiring integrated synthesis capabilities within a small footprint.

Replacement Considerations

The AD9517-4 is a similar device within the same family but features a different VCO tuning range and potentially different output characteristics. Evaluate pin compatibility and register settings when considering cross-model substitution.
