SY89832UMI-TR

Clock Buffers, Drivers Overview

The SY89832UMI-TR is a high-speed, low-skew fanout buffer and translator manufactured by Microchip Technology (formerly Micrel). It operates on a single 2.5V supply with a maximum frequency of 2.5 GHz. The device features one differential input pair and four LVDS output pairs in a 16-pin QFN package. Key electrical parameters include a typical propagation delay of 470 ps at 2.5V, within-device skew under 20 ps, and additive phase jitter of 81 fs RMS at 622 MHz. It supports industrial temperature ranges from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Guaranteed AC performance over temperature with throughput up to 2.5 GHz
• Ultra-low skew design: <20 ps within-device skew and <200 ps part-to-part skew
• Unique patented input termination and VT pin accepting DC- or AC-coupled inputs
• Synchronous enable (EN) input for controlled output state transitions

Clock Buffers, Drivers Applications

• Processor clock distribution networks
• SONET/SDH clock distribution systems
• Fibre Channel clock distribution
• Gigabit Ethernet clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TR' corresponds to the Tape and Reel packaging configuration as specified in the datasheet. Confirm that the component source aligns with the manufacturer's authorized distribution channels to ensure authenticity and compliance with RoHS standards.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:4 fanout ratio with LVDS outputs is required for high-speed signal integrity. Ensure the input signal type matches the supported CML, LVPECL, or LVDS standards via the VT pin interface. Verify that the PCB layout accommodates the 16-pin QFN exposed pad for thermal management.

Clock Buffers, Drivers Part Context

The SY89832U belongs to the Precision Edge® family of high-speed clock generators and translators. This series is designed for applications requiring precise timing synchronization and low jitter performance in telecommunications and computing infrastructure environments.

Clock Buffers, Drivers Replacement Considerations

Consult the manufacturer's documentation for direct cross-references. Potential alternatives within the same family include the SY89833L or SY89833AL, which offer different I/O combinations.
