SY89833LMI-TR

Clock Buffers, Drivers Overview

The SY89833LMI-TR is a 3.3V ultra-precision 1:4 LVDS fanout buffer/translator with internal termination, manufactured by Microchip Technology (formerly Micrel). It operates over an industrial temperature range of -40°C to +85°C and supports throughput frequencies up to 2GHz. The device features guaranteed AC performance including less than 600ps propagation delay, less than 20ps within-device skew, and 98fs RMS phase jitter. It utilizes a 16-pin 3mm x 3mm QFN package and includes a VT pin for flexible input termination interfacing.

Clock Buffers, Drivers Feature Summary

• Ultra-low jitter design with 98fs RMS phase jitter
• Patented Any-In input termination with VT pin accepting DC- and AC-coupled inputs
• Guaranteed within-device skew of less than 20ps over supply voltage and temperature
• High-speed LVDS outputs with typical differential swing of 650mV

Clock Buffers, Drivers Applications

• Processor clock distribution
• SONET clock distribution
• Fibre Channel clock distribution
• Gigabit Ethernet clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'MI' against official documentation, as standard listings typically reference 'LMG'. Confirm current availability status directly with the manufacturer or authorized distributors, as component lifecycle stages may affect procurement options.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring low skew and high-frequency signal distribution in a 3.3V environment. Ensure compatibility with LVDS output standards and verify that the 16-pin QFN package footprint meets PCB layout requirements. Consider thermal dissipation characteristics when designing the heat path for the exposed pad.

Clock Buffers, Drivers Part Context

This part belongs to the Precision Edge family of high-speed clock synchronization devices originally developed by Micrel, which was acquired by Microchip Technology. It serves as a specialized solution for clock distribution networks requiring precise timing alignment and low noise performance.

Clock Buffers, Drivers Replacement Considerations

The SY89832U provides similar functionality but operates from a 2.5V ±5% supply instead of 3.3V. Verify voltage compatibility and pin-to-pin equivalence before substitution.
