SY89872UMI-TR

Clock Buffers, Drivers Overview

The SY89872UMI-TR is a programmable clock divider and fanout buffer from Microchip Technology's Precision Edge series. It accepts any differential input signal, including CML, LVDS, PECL, HSTL, and LVTTL/CMOS, and converts it to LVDS outputs. The device operates at a maximum frequency of 2 GHz with a single-ended output swing of approximately 350 mV and a differential swing of 700 mV. It features internal termination resistors and supports divide-by-1, -2, -4, and -8 ratios. Powered by a 2.5 V supply, it functions within a temperature range of –40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Supports any differential input format (CML, LVDS, PECL, HSTL) plus LVTTL/CMOS
• Programmable divide-by-1, -2, -4, or -8 ratios
• Internal 50Ω input and output termination resistors
• LVDS outputs with 700 mV typical differential swing

Clock Buffers, Drivers Applications

• Clock distribution in high-speed data communication systems
• Frequency division for multi-rate network interfaces
• Signal translation between different logic families

Clock Buffers, Drivers Procurement Notes

Verify the package marking and date code against the manufacturer's latest production notices. Confirm that the specific suffix 'TR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes.

Clock Buffers, Drivers Selection Notes

Select this component when a flexible input interface is required alongside precise frequency division. Ensure the system power rail is stable at 2.5 V ±5% to maintain timing accuracy. Verify that the load capacitance on the LVDS outputs does not exceed the datasheet limits for the desired operating frequency.

Clock Buffers, Drivers Part Context

This part belongs to the SY89872U family of clock dividers and buffers. It is functionally similar to the SY89875U but optimized for 2.5 V operation. The 'UMI' designation indicates the 16-pin MLF package, while 'TR' specifies the reel packaging method.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes include other parts from the SY8987x family such as the SY89875U for similar functionality with potentially different voltage requirements. Cross-reference pinouts and electrical characteristics before substitution.
