AD9520-0BCPZ-REEL7

Overview

The AD9520-0BCPZ-REEL7 is a multi-output clock generator featuring an integrated phase-locked loop (PLL) and voltage-controlled oscillator (VCO). The on-chip VCO tunes from 2.53 GHz to 2.95 GHz, supporting external 3.3 V/5 V VCOs or VCXOs up to 2.4 GHz. It provides twelve 1.6 GHz LVPECL outputs in four groups, each with a 1-to-32 divider and phase delay capability. Outputs can be reconfigured as two 250 MHz CMOS pairs. Additive output jitter is as low as 225 fs rms, with channel-to-channel skew under 16 ps within groups. The device operates on a single 3.3 V supply and includes nonvolatile EEPROM for configuration storage.

Feature Summary

• Integrated PLL and VCO tuning range of 2.53 GHz to 2.95 GHz
• Twelve 1.6 GHz LVPECL outputs with configurable 1-to-32 dividers
• Additive output jitter as low as 225 fs rms
• SPI and I²C compatible serial control port with nonvolatile EEPROM

Applications

• Low jitter, low phase noise clock distribution
• Clock generation for SONET, 10Ge, 10GFC, Synchronous Ethernet, OTU2/3/4
• Forward error correction (G.710)
• Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs
• High performance wireless transceivers and ATE

Procurement Notes

Verify the REEL7 suffix indicates tape and reel packaging when sourcing this component. Confirm the specific revision level against the latest Analog Devices documentation to ensure compatibility with required register configurations and electrical specifications.

Selection Notes

Select the AD9520-0 variant specifically for applications requiring LVPECL outputs; use the AD9522-0 if LVDS drivers are needed instead. Ensure the system design accommodates the 64-lead LFCSP package dimensions and thermal requirements for operation across the −40°C to +85°C industrial temperature range.

Part Context

This part belongs to the AD9520 family of clock generators. The AD9520-0 is distinguished by its internal VCO and LVPECL output drivers. Other variants in the family may feature different output types or VCO configurations. The REEL7 suffix denotes the specific bulk packaging format for automated assembly.

Replacement Considerations

For LVDS output requirements, consider the AD9522-0. For evaluation purposes, the AD9520-0/PCBZ serves as the designated development platform.
