AD9518-1BCPZ

Overview

The AD9518-1BCPZ is a 6-output clock generator featuring an integrated voltage-controlled oscillator (VCO) that tunes from 2.30 GHz to 2.65 GHz. It supports optional external VCO or VCXO inputs up to 2.4 GHz and accepts LVPECL, LVDS, or CMOS reference signals up to 250 MHz. The device provides three pairs of LVPECL outputs operating up to 1.6 GHz, each with programmable dividers ranging from 1 to 32 and coarse phase delay capabilities. Key performance metrics include an additive output jitter of 225 fs rms and channel-to-channel skew of less than 10 ps for paired outputs. It operates on a single 3.3 V supply within the industrial temperature range of −40°C to +85°C.

Feature Summary

• Integrated VCO tuning range of 2.30 GHz to 2.65 GHz
• Three pairs of LVPECL outputs with 1-to-32 programmable dividers
• Additive output jitter of 225 fs rms
• Supports differential or dual single-ended reference inputs

Applications

• Low jitter, low phase noise clock distribution
• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, and MxFE
• High-performance wireless transceivers
• ATE and high-performance instrumentation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required supply voltage ranges and thermal management requirements for the LFCSP-48 package during integration.

Selection Notes

Select this component when subpicosecond jitter performance and low phase noise are critical for data converter applications. Consider the internal VCO range versus external VCXO requirements based on frequency stability needs. Verify that the LVPECL output drivers meet the termination and voltage level requirements of the downstream circuitry.

Part Context

The AD9518-1 is part of the AD9518 family, which includes variants like the AD9516 and AD9517. These devices share similar functionality but differ in package size and the number of available outputs. The AD9518-1 specifically offers six LVPECL outputs in a 48-lead LFCSP package.

Replacement Considerations

The AD9516 and AD9517 are functionally similar members of the same family, differing primarily in package dimensions and output count. Verify pinout compatibility and output configuration requirements before substituting.
