AD9552BCPZ

Overview

The AD9552BCPZ is a fractional-N phase-locked loop (PLL) based clock generator designed to replace high-frequency crystal oscillators. It converts low-frequency input references (6.6 MHz to 112.5 MHz) into high-frequency outputs up to 900 MHz using an on-chip VCO and sigma-delta modulator. The device supports LVPECL, LVDS, or CMOS output logic levels and operates on a single 3.3 V supply with power consumption under 400 mW. It features pin-programmable frequency ratios and an SPI interface for custom configurations, achieving RMS jitter below 0.5 ps.

Feature Summary

• Fractional-N PLL architecture with integrated sigma-delta modulator
• Output frequencies up to 900 MHz with RMS jitter <0.5 ps
• Single 3.3 V supply operation with total current draw of 149 mA to 169 mA
• Supports LVPECL, LVDS, and CMOS output drivers

Applications

• SONET/SDH (including FEC), 10 Gb Ethernet, Fibre Channel
• DRFI/DOCSIS infrastructure
• High-definition video frequency translation
• Wireless infrastructure systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure that any additional characters in the part number do not indicate variations in functionality or testing criteria. Cross-reference the component details with the latest datasheet revision E specifications.

Selection Notes

Select this component when replacing high-frequency VCXOs, OCXOs, or SAW resonators with flexible frequency translation requirements. Ensure the application can accommodate the required external loop filter capacitor and decoupling capacitors for the LDO pins. Verify that the input reference source matches the supported frequency ranges and logic levels.

Part Context

The AD9552BCPZ belongs to the Analog Devices AD9552 family of oscillator frequency upconverters. It utilizes a 5 mm × 5 mm small package size and is specified for the extended industrial temperature range of −40°C to +85°C. The device integrates an on-chip VCO and relies on external components to complete the PLL loop filter circuitry.

Replacement Considerations

Direct replacement requires matching the 3.3 V supply voltage and ensuring compatibility with the existing loop filter design. Verify that the target system supports the required LVPECL, LVDS, or CMOS output termination schemes.
