AD9516-2BCPZ-REEL7

Overview

The AD9516-2BCPZ-REEL7 is a 14-output clock generator featuring an integrated phase-locked loop and voltage-controlled oscillator (VCO). The on-chip VCO operates within the 2.05 GHz to 2.33 GHz range, with support for external VCOs up to 2.4 GHz. It provides six LVPECL outputs capable of frequencies up to 1.6 GHz and four LVDS outputs operating up to 800 MHz. Each LVDS output can be reconfigured as two CMOS outputs up to 250 MHz. The device utilizes a 64-lead LFCSP package and functions over an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated PLL with on-chip VCO tuning from 2.05 GHz to 2.33 GHz
• Six pairs of LVPECL outputs supporting frequencies up to 1.6 GHz
• Four pairs of LVDS outputs supporting frequencies up to 800 MHz
• LVDS outputs configurable as eight single-ended CMOS outputs up to 250 MHz

Applications

• Low jitter clock distribution for high-speed data converters
• Clocking for 10/40/100 Gb/sec networking line cards
• High-performance wireless transceivers
• ATE and high-performance instrumentation systems

Procurement Notes

Verify the REEL7 suffix indicates tape and reel packaging when sourcing this component. Confirm that the specific part number matches the AD9516-2 variant with the integrated 2.2 GHz VCO rather than other family members. Ensure compatibility with the required 64-lead LFCSP footprint during procurement planning.

Selection Notes

Select this model when subpicosecond jitter performance and low phase noise are critical requirements. The internal VCO covers 2.05 GHz to 2.33 GHz; use external VCO options if higher frequencies are needed. Consider the available LVPECL, LVDS, and CMOS output configurations to match the interface requirements of downstream components without additional buffering.

Part Context

This component belongs to the AD9516 family of clock generators manufactured by Analog Devices Inc. The AD9516-2 specifically distinguishes itself through its integrated VCO frequency range of 2.05 GHz to 2.33 GHz. Other variants in the series offer different VCO ranges or feature sets, making the -2 designation essential for identifying the correct electrical characteristics.

Replacement Considerations

Direct replacements within the same family include the AD9516-0, AD9516-3, and AD9516-4. These alternatives share the 64-lead LFCSP package but differ in VCO frequency ranges and specific output capabilities. Verify that the substitute's VCO range and output types align with the original design specifications.
