SY100E310LJI-TR

Clock Buffers, Drivers Overview

The SY100E310LJI-TR is a 3.3V precision 2:8 ECL/PECL fanout buffer manufactured by Microchip Technology (formerly Micrel). It features fully differential clock paths to minimize device and system skew, achieving within-device skew of less than 50ps. The device includes a 2:1 multiplexer input for redundant switchover applications. It operates on a +3.3V supply with an operating temperature range of -40°C to +85°C. The maximum operating frequency is typically greater than 800MHz. It is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

• Optimized for 3.3V LVPECL or LVECL operation
• Internal 75kΩ pull-down resistors

Clock Buffers, Drivers Applications

• Communications clock distribution
• Redundant clock switchover
• High-end server clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the component status as the original manufacturer Micrel was acquired by onsemi. Confirm if the specific SY100E310LJI-TR part number is still actively produced or if it has been superseded by newer equivalents. Check RoHS compliance requirements against the datasheet's Pb-Free recommendations for new designs.

Clock Buffers, Drivers Selection Notes

Select this component when low-skew clock distribution is critical for systems requiring up to 8 outputs from 2 inputs. Ensure the design supports 3.3V power supplies and PECL/ECL logic levels. Verify that the 28-pin PLCC package fits the PCB layout constraints and that the thermal resistance characteristics are suitable for the application environment.

Clock Buffers, Drivers Part Context

This component belongs to the SY100E series of high-speed clock buffers. It serves as a pin-for-pin replacement for the MC100LVE310. The 'L' suffix indicates the leaded PLCC package, while 'TR' denotes tape and reel packaging. The product line focuses on precision timing solutions for high-frequency digital systems.

Clock Buffers, Drivers Replacement Considerations

The datasheet lists the MC100LVE310FN and MC100LVE310FNR2 as cross-reference parts. These are functionally equivalent components available from onsemi.
