AD9522-0BCPZ-REEL7

Overview

The AD9522-0BCPZ-REEL7 is a 12-channel clock generator featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 2.53 GHz to 2.95 GHz. It supports external VCOs up to 2.4 GHz and accepts reference inputs from CMOS, LVPECL, or LVDS sources up to 250 MHz. The device provides twelve 800 MHz LVDS outputs, each configurable as two 250 MHz CMOS outputs. Key specifications include additive output jitter as low as 242 fs rms and channel-to-channel skew under 60 ps within grouped outputs. It operates on a single 3.3 V supply and includes nonvolatile EEPROM for configuration storage.

Feature Summary

• Integrated VCO tunes from 2.53 GHz to 2.95 GHz
• Twelve 800 MHz LVDS outputs reconfigurable as 24 CMOS outputs
• Additive output jitter as low as 242 fs rms
• SPI and I2C compatible serial control port with onboard EEPROM

Applications

• Low jitter, low phase noise clock distribution
• Clock generation for SONET, 10Ge, and 10G FC protocols
• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, and MxFEs
• High performance wireless transceivers
• ATE and high performance instrumentation

Procurement Notes

Verify the REEL7 suffix indicates tape-and-reel packaging containing 750 units per manufacturer standard package. Confirm the LFCSP-64 package type and industrial temperature range (-40°C to +85°C). Ensure compatibility with 3.3 V logic levels for SPI/I2C interfaces. Check for moisture sensitivity requirements during storage and handling.

Selection Notes

Select this variant when an internal VCO frequency range of 2.53 GHz to 2.95 GHz is required. Compare against AD9522-1 (2.27–2.65 GHz), AD9522-2 (2.02–2.335 GHz), and AD9522-4 (1.4–1.8 GHz) if different internal tuning ranges are needed. Consider the AD9520-0 equivalent if LVPECL drivers are preferred over LVDS. Verify external VCO support up to 2.4 GHz if using off-chip oscillators.

Part Context

The AD9522-0 is part of the AD9522 family of multi-output clock generators. It shares the same pinout and functionality as other variants in the series, differing primarily in the frequency range of the integrated VCO. The AD9520-0 serves as the LVPECL/CMOS driver equivalent. All variants utilize the 64-lead LFCSP package and support identical serial control interfaces.

Replacement Considerations

Public confirmed substitute part numbers: AD9522-1BCPZ, AD9522-2BCPZ, AD9522-4BCPZ. These variants share the same package and interface but offer different internal VCO tuning ranges. The AD9520-0BCPZ is functionally equivalent but uses LVPECL/CMOS drivers instead of LVDS/CMOS.
