SY89202UMI-TR

Clock Buffers, Drivers Overview

The SY89202UMI-TR is a precision, high-speed integrated clock divider and LVPECL fanout buffer manufactured by Microchip Technology. It supports clock frequencies up to 1.5 GHz with an internal input termination architecture compatible with AC- or DC-coupled signals as small as 100mV. The device features three independently controlled output banks configurable for ÷1, ÷2, or ÷4 divide ratios. Key electrical parameters include a maximum propagation delay of 930 ps, within-bank skew of 25 ps, and total jitter under 10 ps peak-to-peak. It operates on a 2.5V ±5% or 3.3V ±10% supply in a 32-pin QFN package.

Clock Buffers, Drivers Feature Summary

• Three low-skew LVPECL output banks with programmable ÷1, ÷2, and ÷4 divider options
• Ultra-low jitter design: <1ps RMS random jitter and <10ps PP total jitter
• Patent-pending input termination accepts AC- and DC-coupled inputs (CML, PECL, LVDS)
• Internal input termination eliminates external resistor networks

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' corresponds to the Tape and Reel packaging format specified in the datasheet. Confirm that the 'MI' designation aligns with the industrial temperature range (-40°C to +85°C) and QFN-32 package type. Ensure compatibility with the required power supply voltage (2.5V or 3.3V) and check for any specific lead finish requirements such as NiPdAu.

Clock Buffers, Drivers Selection Notes

Select this component when phase-matched clock distribution with flexible division ratios is required. The device handles differential inputs down to 100mV without level shifting. Ensure the application requires LVPECL outputs with 800mV swing. Verify that the 32-pin QFN package fits the PCB layout constraints and thermal requirements.

Clock Buffers, Drivers Part Context

The SY89202U belongs to Micrel’s Precision Edge product family, now part of Microchip Technology. It serves as a high-performance solution for clock distribution in communication systems. The device integrates divider logic and fanout buffering to reduce board space and component count compared to discrete solutions.

Clock Buffers, Drivers Replacement Considerations

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