AD9517-2BCPZ

Overview

The AD9517-2BCPZ is a 12-output clock generator from Analog Devices, housed in a 48-lead LFCSP package. It integrates a phase-locked loop and a voltage-controlled oscillator (VCO) with a tuning range of 2.05 GHz to 2.33 GHz. The device supports an external VCO or VCXO up to 2.4 GHz. It provides two pairs of LVPECL outputs operating up to 1.6 GHz and two pairs of LVDS outputs operating up to 800 MHz. Each LVDS output can be reconfigured as two CMOS outputs operating up to 250 MHz. The component 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 2.05 GHz to 2.33 GHz
• Supports external VCO/VCXO inputs up to 2.4 GHz
• Provides four LVPECL outputs (up to 1.6 GHz) and four LVDS outputs (up to 800 MHz)
• Reconfigurable LVDS outputs allow for eight additional CMOS outputs (up to 250 MHz)

Applications

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

Procurement Notes

Verify the specific suffix BCPZ against the manufacturer's current ordering guide to confirm package type and lead-free status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the design accounts for the required 3.3 V power supply and appropriate termination networks for LVPECL and LVDS interfaces.

Selection Notes

Select the AD9517-2BCPZ when subpicosecond jitter performance and low phase noise are critical for data converter applications. Choose this model over the AD9516 or AD9518 if the specific combination of LVPECL and LVDS/CMOS outputs is required. Ensure the system reference input matches the supported LVPECL, LVDS, or CMOS formats up to 250 MHz.

Part Context

The AD9517-2 is part of the AD9517 family, which also includes the AD9516 and AD9518. These variants share similar internal architectures but differ in package size and output configurations. The AD9517-2 specifically offers a balanced mix of high-speed differential outputs suitable for complex multi-channel timing requirements.

Replacement Considerations

The AD9516 and AD9518 are functionally similar members of the same family but feature different output combinations and package sizes. For applications requiring crystal reference inputs or EEPROM configuration, the AD9520 and AD9522 are available alternatives.
