SY100E111LJC

Clock Buffers, Drivers Overview

The SY100E111LJC is a low skew 1-to-9 differential clock driver manufactured by Micrel, Inc. It operates with 5V or 3.3V power supplies and accepts one signal input to fan out to nine identical differential outputs. The device features a VBB output for single-ended input compatibility and includes internal 75KΩ input pulldown resistors. Designed for high-performance clock distribution, it guarantees part-to-part skew of 200ps and output-to-output skew of 50ps. It is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

• Low skew design with 50ps output-to-output skew and 200ps part-to-part skew
• Supports both 5V and 3.3V power supply options
• Differential input and output architecture with VBB reference output
• Internal 75KΩ input pulldown resistors

Clock Buffers, Drivers Applications

• High-performance clock distribution on backplanes
• Board-level clock distribution systems
• PECL environment applications requiring low jitter

Clock Buffers, Drivers Procurement Notes

Verify the component status as the datasheet indicates 'NOT RECOMMENDED FOR NEW DESIGNS'. Confirm that the specific ordering suffix LJC corresponds to the Commercial temperature range and J28-1 package type. Ensure compliance with lead finish specifications (Sn-Pb) if RoHS compliance is required for the target application.

Clock Buffers, Drivers Selection Notes

Select this component when low skew is critical for clock distribution networks. Ensure the system supports either 5V or 3.3V PECL operation. Designers must terminate all unused differential pairs on the same package side as active pairs to maintain minimum skew specifications. Verify that the commercial temperature range meets the environmental requirements.

Clock Buffers, Drivers Part Context

This component belongs to the Precision Edge® SY10/100E111A/L family from Micrel, Inc. It is functionally similar to the popular SY10/100E111 but offers improved performance with lower jitter and low voltage operation capabilities. The product line is designed to minimize gate-to-gate skew through optimal layout and empirical modeling.
