SY89832UMG-TR

Clock Buffers, Drivers Overview

The SY89832UMG-TR is a high-speed, low-skew fanout buffer and translator manufactured by Microchip Technology. It operates on a single 2.5V supply (2.375V to 2.625V) and supports input frequencies up to 2.5 GHz. The device features one differential input pair accepting CML, LVDS, or LVPECL signals, and provides four differential LVDS outputs. Key electrical parameters include a maximum propagation delay of 570 ps at 2.5V, within-device skew less than 20 ps, and additive phase jitter of 81 fs RMS at 622 MHz. It is housed in a 16-pin QFN package.

Clock Buffers, Drivers Feature Summary

• Guaranteed AC performance over temperature with DC-to >2.0 GHz throughput
• Ultra-low skew: <20 ps within-device and <200 ps part-to-part
• Unique patented input termination and VT pin for flexible interface design
• Accepts AC-coupled or DC-coupled inputs from various logic standards

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 format as specified in the datasheet. Confirm that the component meets RoHS compliance requirements. Ensure the industrial temperature range (-40°C to +85°C) aligns with the target application environment before finalizing procurement specifications.

Clock Buffers, Drivers Selection Notes

Select this component when interfacing between different voltage domains or logic families requiring translation to LVDS. The internal 50Ω input termination simplifies circuit design compared to external termination solutions. Ensure the power supply bypassing uses low ESR capacitors placed close to VCC pins to maintain signal integrity at frequencies up to 2.5 GHz.

Clock Buffers, Drivers Part Context

This component belongs to Micrel's Precision Edge® family of high-speed clock generators and translators. The manufacturer was acquired by Microchip Technology, which continues to support the product line. The device serves as a critical timing element in high-speed serial communication and data processing architectures requiring precise clock synchronization.

Clock Buffers, Drivers Replacement Considerations

Consult the official documentation for compatible alternatives such as the SY89833L or SY89833AL for applications requiring 3.3V operation instead of the 2.5V supply used by the SY89832U.
