SY89464UMG

Clock Buffers, Drivers Overview

The SY89464UMG is a high-performance clock multiplexer from the Precision Edge series, designed for demanding applications. It integrates a low jitter 1:10 LVPECL fanout buffer with a 2:1 differential input multiplexer optimized for redundant source switchover applications. The device operates within a supply voltage range of 2.375V to 2.625V and supports frequencies up to 2 GHz. It is housed in a 44-VFQFN Exposed Pad package.

Clock Buffers, Drivers Feature Summary

• Integrates a 2:1 differential input multiplexer with a 1:10 LVPECL fanout buffer
• Optimized for redundant source switchover applications
• Features low jitter performance for high-frequency clock signal processing

Clock Buffers, Drivers Applications

• Redundant source switchover systems
• High-frequency clock signal multiplexing
• Clock distribution networks requiring low jitter

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix (e.g., TR) against your packaging requirements, as the base part number may correspond to tape-and-reel or tube configurations depending on the distributor listing. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly planning. Ensure the 44-MLF package dimensions match your PCB footprint design constraints.

Clock Buffers, Drivers Selection Notes

Select this component when a combined multiplexer and fanout buffer solution is required for LVPECL signals. The integrated design reduces board space compared to discrete components. Consider the 2:1 MUX ratio for redundancy switching and the 1:10 output capability for distributing the selected clock source across multiple loads.

Clock Buffers, Drivers Part Context

This part belongs to Microchip's Precision Edge series, which focuses on high-speed clock management solutions. The SY89464U family typically includes variants like the SY89464UMY and SY89465UMG, offering similar functionalities with slight variations in packaging or specific electrical characteristics tailored for different system integration needs.

Clock Buffers, Drivers Replacement Considerations

The SY89465UMG is listed as a parameter-equivalent substitute. Verify pin compatibility and specific electrical tolerances before swapping, as differences in internal circuitry may affect performance in sensitive timing applications.
