SY100E111LJY-TR

Clock Buffers, Drivers Overview

The SY100E111LJY-TR is a low skew 1-to-9 differential clock driver manufactured by Microchip Technology under the Precision Edge series. It operates with 5V or 3.3V power supplies and accepts one signal input, which can be differential or single-ended using the VBB output. The device fans out the signal to nine identical differential outputs. Key specifications include a part-to-part skew of 200ps and an output-to-output skew of 50ps. It features voltage and temperature compensated outputs, 75KΩ input pulldown resistors, and is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

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

Clock Buffers, Drivers Applications

• High performance clock distribution across backplanes
• Board-level clock distribution in +5V/+3.3V systems
• PECL environment applications requiring low jitter

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as this is a specialized logic IC. Confirm RoHS compliance status via official documentation, noting that the 'Y' suffix indicates a Pb-Free package with a matte tin finish. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Clock Buffers, Drivers Selection Notes

Select this component when low skew is critical for clock distribution networks. Ensure termination requirements are met by terminating both sides of differential outputs into 50Ω loads to maintain specified skew margins. Verify compatibility with existing PECL or ECL logic levels in the target system design.

Clock Buffers, Drivers Part Context

This device belongs to the SY10/100E111A/L family, designed specifically for low skew performance. It serves as a functional improvement over earlier models by offering lower jitter and low voltage operation capabilities while maintaining full compatibility with standard Motorola MC100LVE111 interfaces.

Clock Buffers, Drivers Replacement Considerations

The datasheet explicitly states the device is fully compatible with the Motorola MC100LVE111. Designers may consider this equivalent part number for direct replacement purposes without significant circuit modifications.
