AD9522-2BCPZ

Overview

The AD9522-2BCPZ is a low phase noise clock generator featuring an integrated voltage-controlled oscillator (VCO) with a tuning range of 2.02 GHz to 2.335 GHz. It supports external 3.3 V/5 V VCOs or VCXOs up to 2.4 GHz. The device provides twelve 800 MHz LVDS outputs, which can be reconfigured as twenty-four 250 MHz CMOS outputs. Additive output jitter is as low as 242 fs rms, with 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 2.02 GHz to 2.335 GHz; supports external VCO/VCXO up to 2.4 GHz
• Twelve 800 MHz LVDS outputs divided into four groups, each with 1-to-32 divider and phase delay
• Additive output jitter as low as 242 fs rms; channel-to-channel skew < 60 ps
• SPI- and I²C-compatible serial control port with in-package nonvolatile EEPROM

Applications

• Low jitter, low phase noise clock distribution
• Clock generation for SONET, 10Ge, 10G FC, and other 10 Gbps protocols
• Forward error correction (G.710)
• Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs
• High performance wireless transceivers and ATE

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 64-lead LFCSP package variant. Confirm that the ordering code matches the Rev. A datasheet specifications for the AD9522-2 family member. Ensure environmental compliance documentation aligns with RoHS standards if required for the target application.

Selection Notes

Select this part when subpicosecond jitter performance and flexible reference inputs are required. The internal VCO range of 2.02 GHz to 2.335 GHz suits applications needing precise frequency synthesis without external oscillators. Consider the AD9520-2 equivalent if LVPECL drivers are preferred over LVDS. Verify power supply constraints against the 3.135 V to 3.465 V operating range.

Part Context

The AD9522-2 is a member of the AD9522 family, distinguished by its specific integrated VCO tuning range of 2.02 GHz to 2.335 GHz. It shares the same 64-lead LFCSP package and functional architecture as other variants like the AD9522-0 and AD9522-1, but differs in VCO specifications. The AD9520-2 serves as an equivalent part utilizing LVPECL drivers instead of LVDS.

Replacement Considerations

The AD9520-2 is an equivalent part offering LVPECL/CMOS drivers instead of LVDS/CMOS drivers. Other AD9522 family members share the same package and control interface but differ in integrated VCO frequency ranges.
