SY100EL15LZC-TR

Clock Buffers, Drivers Overview

The SY100EL15LZC-TR is a low skew 1:4 clock distribution IC designed for Precision Edge applications. It supports differential or single-ended ECL/PECL inputs and features a multiplexed clock input for lower speed scan or test clocks alongside high-speed system clocks. The device includes a synchronous enable/disable function to prevent runt clock pulses. Operating on a 3.3V supply, it delivers 50ps output-to-output skew with propagation delays ranging from 410ps to 750ps depending on the input source. It is housed in a 16-pin SOIC package.

Clock Buffers, Drivers Feature Summary

• Low skew 1:4 clock distribution with 50ps within-device skew
• Multiplexed clock input supporting differential or single-ended ECL/PECL signals
• Synchronous enable/disable control to avoid runt clock pulses
• Internal 75KΩ input pull-down resistors

Clock Buffers, Drivers Applications

• Low skew clock distribution networks
• High-speed system clock distribution
• Scan or test clock distribution integration

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'ZC' corresponds to the commercial temperature range (-40°C to +85°C) and Sn-Pb lead finish as defined in the manufacturer's documentation. Confirm that the tape and reel packaging matches the 'TR' designation if bulk quantities are required. Ensure compatibility with the 3.3V power supply specifications before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:4 fanout buffer with minimal skew is required for ECL or PECL logic families. The synchronous enable feature is critical for systems requiring glitch-free clock gating. Verify that the input signal swing meets the minimum 250mV requirement and that the operating voltage aligns with the -3.0V to -3.8V VEE range for optimal performance.

Clock Buffers, Drivers Part Context

This part belongs to the SY100EL series of Precision Edge clock drivers originally developed by Micrel, Inc., which was later acquired by Microchip Technology. The 'ZC' suffix indicates the commercial temperature grade and standard lead finish, while 'TR' denotes tape and reel packaging. It serves as a specialized timing solution within the broader logic IC portfolio.
