SY100EL34ZC-TR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SY100EL34ZC-TR is a low skew ÷2, ÷4, and ÷8 clock generation chip designed for precise timing applications. It features synchronous internal dividers that align common output edges with 50ps maximum within-device skew. The device supports differential or single-ended ECL/PECL inputs and includes a VBB reference output for AC-coupled sinusoidal sources. Key electrical parameters include a propagation delay of 960–1200 ps (typical 1100 ps) and an operating supply voltage range of -4.2V to -5.5V. It operates within a commercial temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm package type and temperature range. Confirm availability status as this component may be subject to lifecycle changes. Ensure the selected variant matches the required power supply voltage range (-4.2V to -5.5V for standard EL34).

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the SY100EL34ZC-TR when low skew performance is critical for multi-phase clock distribution. Choose this part over asynchronous dividers to ensure synchronized outputs. Verify compatibility with existing ECL/PECL drivers and ensure the PCB layout accommodates the 16-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the ClockWorks™ SY10/100EL34/L series, which are specialized clock generation chips. The 'SY100' prefix typically denotes the 5V compatible version, while 'L' variants support 3.3V operation. The 'ZC' suffix indicates a 16-lead SOIC package in a commercial temperature grade.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 16-pin SOIC footprint and provide ÷2, ÷4, ÷8 division capabilities. Check for equivalent skew specifications (<50ps) and compatible input/output voltage levels. Verify pinout compatibility before substitution.
