SY100E111LJY

Clock Buffers, Drivers Overview

The SY100E111LJY is a low skew 1-to-9 differential clock driver from the Precision Edge series, designed for high-performance clock distribution. It accepts one signal input and fans it out to nine identical differential outputs without an enable pin. The device supports both 5V and 3.3V power supply options, operating in PECL mode with VEE grounded. Key electrical characteristics include a typical part-to-part skew of 200ps and output-to-output skew of 50ps. It features voltage and temperature compensated outputs, a VBB reference output, and 75KΩ input pulldown resistors. The component is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

• 1:9 Differential Clock Driver (w/o Enable)
• Low Skew: 200ps part-to-part, 50ps output-to-output
• Supports 5V and 3.3V Power Supplies
• Voltage and Temperature Compensated Outputs

Clock Buffers, Drivers Applications

• High performance clock distribution across backplanes
• Board-level clock distribution in +5V/+3.3V systems
• Systems incorporating GTL parallel termination

Clock Buffers, Drivers Procurement Notes

Verify RoHS compliance status as the 'Y' suffix indicates a Pb-Free package with a matte tin finish and bar-line indicator. Confirm that the specific revision matches the required lead finish and moisture sensitivity level (Level 1). Check for obsolescence or lifecycle status changes from the original manufacturer Micrel or current rights holder.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:9 fanout buffer is required without an enable function. Ensure the design can accommodate the requirement to terminate all unused differential pairs on the same package side as active pairs to maintain specified skew margins. Verify compatibility with existing PECL logic levels and power supply rails (3.3V or 5V).

Clock Buffers, Drivers Part Context

This part belongs to the SY10/100E111A/L family, which improves upon the earlier SY10/100E111 by offering lower jitter and low voltage operation capabilities. The '100' prefix typically denotes industrial temperature range variants compared to the '10' prefix. The device is fully compatible with the Motorola MC100LVE111 functional specification.

Clock Buffers, Drivers Replacement Considerations

The datasheet states full compatibility with the Motorola MC100LVE111. Designers should verify pinout and electrical parameter equivalence before substitution.
