SY89202UMG-TR

Clock Buffers, Drivers Overview

The SY89202UMG-TR is a precision, high-speed integrated clock divider and LVPECL fanout buffer manufactured by Microchip Technology. It supports maximum output toggle frequencies up to 1.5GHz with an internal input termination architecture compatible with CML, PECL, and LVDS signals. The device features three independently programmable output banks capable of ÷1, ÷2, or ÷4 divide ratios. Key electrical parameters include a propagation delay of less than 930ps, rise/fall times under 220ps, and ultra-low jitter specifications of less than 1ps RMS random jitter and 10ps peak-to-peak total jitter.

Clock Buffers, Drivers Feature Summary

• Three low-skew LVPECL output banks with programmable ÷1, ÷2, and ÷4 divider options
• Internal input termination accepting AC- or DC-coupled signals as small as 100mV (CML, PECL, LVDS)
• Ultra-low jitter design: <1ps RMS random jitter and <10ps PP total jitter
• Guaranteed AC performance over temperature and voltage for frequencies exceeding 1.5GHz

Clock Buffers, Drivers Applications

• SONET/SDH channel select applications
• Fibre Channel multi-channel select applications
• Gigabit Ethernet multi-channel select applications

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TR' confirms the tape and reel packaging format required for automated assembly processes. Confirm that the component meets RoHS3 compliance standards and operates within the specified industrial temperature range of -40°C to +85°C. Ensure the supply voltage aligns with the 2.5V ±5% or 3.3V ±10% operating ratings defined in the datasheet.

Clock Buffers, Drivers Selection Notes

Select this component when a high-speed clock distribution solution requires flexible frequency division alongside signal buffering. The device is suitable for designs needing phase-matched outputs across multiple banks with minimal skew. Consider the 32-pin QFN package constraints and thermal resistance characteristics if operating in still-air environments without active cooling.

Clock Buffers, Drivers Part Context

This part belongs to Micrel’s Precision Edge® product family, which was acquired by Microchip Technology. The SY89202U series is designed specifically for communications applications requiring precise timing control. It serves as a specialized interface between high-frequency clock sources and downstream logic circuits requiring divided and buffered signals.

Clock Buffers, Drivers Replacement Considerations

The SY89200U is a related product offering similar functionality but utilizes LVDS outputs instead of LVPECL. Verify output compatibility before substitution.
