MX852EB0027-TR

Overview

The MX852EB0027-TR is a ClockWorks FUSION CMIC device integrating a quartz crystal, synthesizer, and fanout buffers in a single 38-pin 5mm x 7mm LGA package. It generates five 100MHz HCSL outputs with typical phase noise of 200fs (12kHz-20MHz) and 100fs (1.875MHz-20MHz). The unit operates on 2.5V or 3.3V supplies, maintains ±50ppm total stability, and functions within -40°C to +85°C. This configuration delivers an ultra-low jitter clocking solution suitable for high-speed digital interfaces.

Feature Summary

• Integrates quartz crystal, PLL synthesizer, and fanout buffers in one 38-pin LGA package
• Generates five 100MHz differential HCSL clock outputs
• Typical phase noise performance: 200fs (12kHz-20MHz) and 100fs (1.875MHz-20MHz)
• ±50ppm total frequency stability over temperature range (-40°C to +85°C)

Applications

• PCI-Express systems
• Storage controller architectures

Procurement Notes

Verify the TR suffix indicates Tape and Reel shipping format. Confirm the component is sourced from authorized distributors to ensure authenticity. Check current availability status as inventory levels fluctuate. Ensure the ordering part number matches the specific electrical requirements for the target design.

Selection Notes

Select this model when a complete integrated clock chain is required without external crystals. Verify that the 100MHz HCSL output logic meets the input specifications of downstream components. Ensure the PCB layout supports the 38-pin LGA package dimensions and thermal dissipation requirements for the exposed pad connection.

Part Context

This component belongs to the Micrel ClockWorks FUSION family, which consolidates multiple clock generation stages into a single footprint. The MX852EB0027 variant specifically targets applications requiring low jitter and high stability. The -TR suffix denotes the tape and reel packaging option for automated assembly processes.

Replacement Considerations

Direct replacements must match the 38-pin 5mm x 7mm LGA package and 100MHz HCSL output characteristics. Verify pin compatibility and power supply requirements before substitution. Cross-reference with other devices in the ClockWorks FUSION family if functional equivalents are needed.
