AD9522-1BCPZ-REEL7

Overview

The AD9522-1BCPZ-REEL7 is a 12-channel clock generator with an integrated voltage-controlled oscillator (VCO) and phase-locked loop (PLL). It provides 12 LVDS outputs or 24 CMOS outputs, supporting frequencies up to 800 MHz for LVDS and 250 MHz for CMOS. The on-chip VCO tunes from 2.27 GHz to 2.65 GHz, while external VCO/VCXO support extends up to 2.4 GHz. Key electrical parameters include a 3.3 V supply voltage, -40°C to +85°C operating temperature range, and additive output jitter as low as 242 fs rms. The device features configurable channel dividers (1-to-32), reference monitoring, and glitch-free switchover capabilities.

Feature Summary

• Integrated PLL and VCO tuning range of 2.27 GHz to 2.65 GHz
• 12 LVDS outputs (up to 800 MHz) or 24 CMOS outputs (up to 250 MHz)
• Additive output jitter as low as 242 fs rms
• Supports external 3.3 V/5 V VCO/VCXO up to 2.4 GHz

Applications

• Clock generation for SONET, 10Ge, and 10G FC protocols
• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, and MxFEs
• Forward error correction (G.710) systems
• High-performance wireless transceivers

Procurement Notes

Verify the REEL7 suffix indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance and moisture sensitivity levels against current manufacturing data sheets. Ensure the specific revision matches design requirements for serial interface compatibility and register configurations.

Selection Notes

Select this component for applications requiring subpicosecond jitter performance and multiple synchronized clock outputs. Compare with the AD9520-1 if LVPECL drivers are preferred over LVDS. Ensure the external loop filter design supports the desired PLL bandwidth and that the power supply meets the 3.3 V ± 5% requirement.

Part Context

The AD9522-1 is part of the AD9522 family of clock generators. It shares functional similarities with the AD9522-0, AD9522-2, and AD9522-3, differing primarily in the internal VCO frequency tuning range. The AD9520-1 serves as a pin-compatible alternative utilizing LVPECL drivers instead of LVDS.

Replacement Considerations

The AD9522-0BCPZ-REEL7 and AD9522-2BCPZ-REEL7 are functionally similar members of the same family but feature different internal VCO tuning ranges. Verify frequency planning requirements before substitution.
