SY10E111LJC-TR

Clock Buffers, Drivers Overview

The SY10E111LJC-TR is a Precision Edge differential clock driver manufactured by Microchip Technology, housed in a 28-pin PLCC package. It provides one-to-nine fanout with guaranteed part-to-part skew of 200ps and within-device skew of 50ps. The device supports both 5V and 3.3V power supplies, operating in ECL or PECL modes. Key features include voltage and temperature compensated outputs, internal 75KΩ input pulldown resistors, and a VBB output reference. It is fully compatible with Motorola MC100LVE111 standards.

Clock Buffers, Drivers Feature Summary

• Low skew performance: 50ps within-device skew and 200ps part-to-part skew
• Dual supply options: Supports 5V (ECL/PECL) and 3.3V (PECL) operation
• Differential design: Accepts differential or single-ended inputs via VBB output
• Internal circuitry: Includes 75KΩ input pulldown resistors and VBB reference

Clock Buffers, Drivers Applications

• High-performance clock distribution across backplanes
• Board-level low skew clock distribution systems
• Systems requiring compatibility with Motorola MC100LVE111 standards

Clock Buffers, Drivers Procurement Notes

Verify the commercial temperature range associated with the 'C' suffix against application requirements. Confirm that the tape and reel packaging matches automated assembly needs. Ensure the Sn-Pb lead finish is acceptable for the target manufacturing process. Check current availability status as this component may be subject to lifecycle changes.

Clock Buffers, Drivers Selection Notes

Select the SY10E111LJC-TR when low skew is critical for clock distribution networks. Choose this model over non-L variants if tighter skew specifications are required. Ensure termination resistors are applied to all unused differential pairs on the same package side to maintain specified skew margins. Verify power supply voltage levels match either the 5V or 3.3V PECL/ECL configurations.

Clock Buffers, Drivers Part Context

This component belongs to the Precision Edge SY10/100E111A/L family, which improves upon the original SY10/100E111 series by offering lower jitter and low-voltage operation capabilities. The 'L' suffix indicates support for 3.3V logic levels alongside standard 5V operation. The 'J' denotes the 28-pin PLCC package, while 'C' specifies the commercial temperature range.

Clock Buffers, Drivers Replacement Considerations

The SY10E111LJC-TR is functionally equivalent to the Motorola MC100LVE111. Designers should verify pinout compatibility and electrical characteristics before substitution. Other members of the SY10E111 family, such as the AJI or LJI variants, offer different temperature ranges or lead finishes but share the same core functionality.
