AD9520-1BCPZ

Overview

The AD9520-1/PCBZ is an evaluation board designed for the Analog Devices AD9520-1 PLL clock synthesizer. This device features a 12 LVPECL and 24 CMOS output architecture with sub-picosecond jitter performance. It integrates a phase-locked loop (PLL) and a voltage-controlled oscillator (VCO) with a tuning range of 2.27 GHz to 2.65 GHz. The system supports external VCOs up to 2.4 GHz and utilizes SPI or I2C serial interfaces for configuration, including non-volatile EEPROM storage for register settings.

Feature Summary

• Compact platform for evaluating all AD9520-1 features
• Supports internal VCO tuning from 2.27 GHz to 2.65 GHz
• Compatible with external 3.3V/5V VCO/VCXO up to 2.4 GHz
• Features on-board PLL loop filter and USB connectivity

Applications

• Clocking analog-to-digital and digital-to-analog converters up to 2.9 GHz
• Networking and communications line cards
• Test and measurement equipment
• Wireless base stations and controllers
• Clock cleanup and jitter attenuation

Procurement Notes

Verify that the specific revision matches the required hardware version. Confirm software compatibility with the operating system, noting that 64-bit Windows versions are not supported. Ensure the package includes necessary documentation and cables for initial setup and evaluation.

Selection Notes

Select this board specifically for evaluating the AD9520-1 variant. Note that while the board supports the broader AD9520 family, configurations for other variants may require adjusting divider ratios to match their specific VCO frequency ranges. The AD9520-5 lacks an internal VCO, requiring different evaluation procedures.

Part Context

This evaluation board is part of the AD9520 product series, which includes models AD9520-0 through AD9520-5. These devices are low-noise PLL clock synthesizers featuring integrated VCOs, clock dividers, and up to 24 outputs. The series provides automatic holdover and flexible reference input circuits for smooth switching.

Replacement Considerations

The AD9522-0 is functionally identical but features LVDS outputs instead of LVPECL. For alternative evaluation platforms within the same family, refer to boards designated for AD9520-0, AD9520-2, AD9520-3, AD9520-4, or AD9520-5.
