SY100EL14VZI-TR

Clock Buffers, Drivers Overview

The SY100EL14V is a low-skew, 1:5 clock distribution chip designed for systems operating with 3.3V to 5.0V supplies. It accepts differential or single-ended ECL/PECL inputs and features a multiplexed clock input for scan/test clock distribution. The device includes a synchronous enable/disable function to prevent runt pulses. Electrical specifications include a typical output-to-output skew of 30ps (max 50ps) and 70fs RMS additive phase jitter at 622MHz. Operating voltage ranges from -3.0V to -5.5V for VEE, with an ambient temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Low-skew 1:5 clock distribution with typical 30ps output-to-output skew
• Multiplexed clock input supporting differential, single-ended, or scan clocks
• Synchronous enable/disable control via /EN pin
• 70fs RMS typical additive phase jitter at 622MHz carrier frequency

Clock Buffers, Drivers Applications

• Processor clock distribution
• SONET clock distribution
• Fibre Channel clock distribution
• Gigabit Ethernet clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation. The 'Z' indicates a 20-pin SOIC package, while 'G' denotes Pb-free status with NiPdAu lead finish. Confirm whether the '-TR' suffix is required for tape and reel packaging, as standard versions may come in tubes. Ensure the component source matches Micrel specifications.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring low-jitter clock distribution with multiplexing capabilities. Verify that the system supply voltage falls within the 3.3V to 5.0V range. Ensure the design accommodates the synchronous enable logic, which disables outputs only on the negative clock edge. Check thermal requirements, as the SOIC package has a junction thermal resistance of 58°C/W.

Clock Buffers, Drivers Part Context

The SY100EL14V belongs to the SY100E series of high-speed logic devices originally manufactured by Micrel, which was acquired by Microchip Technology. This part functions specifically as a clock buffer and distributor, distinct from shift registers or level translators found in other series members like the SY100E141 or SY100H601.

Clock Buffers, Drivers Replacement Considerations

Direct replacements must match the 1:5 fan-out, ECL/PECL compatibility, and 20-pin SOIC package. Verify that any substitute supports the same multiplexed input functionality and synchronous enable features. Cross-reference electrical parameters such as skew and propagation delay to ensure signal integrity is maintained.
