SY100S834LZC

Clock Generators, PLLs, Frequency Synthesizers Overview

The SY100S834LZC is a low skew clock generation chip from the Precision Edge series, manufactured by Micrel. It provides synchronous divide-by-2, divide-by-4, and divide-by-8 outputs or divide-by-1, divide-by-2, and divide-by-4 outputs based on the Function Select (FSEL) pin state. The device supports differential or single-ended ECL/PECL inputs and operates with a 3.3V power supply. Key electrical parameters include a maximum output-to-output skew of 50ps, a typical propagation delay of 1100ps, and a power supply current of approximately 49mA at 25°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Configurable clock division ratios: ÷1/÷2/÷4 or ÷2/÷4/÷8 via FSEL input
• Low output-to-output skew of 50ps maximum
• Synchronous enable/disable and master reset capabilities
• Supports differential/single-ended ECL and PECL input signals

Clock Generators, PLLs, Frequency Synthesizers Applications

• Low skew clock generation for high-speed digital systems
• Synchronization of internal divider stages in multi-clock architectures
• Systems requiring precise alignment of common output edges

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized channels as this part originates from Micrel. Confirm package marking matches SY100S834LZC and check lead finish specifications. Ensure compatibility with existing design constraints regarding the Z16-2 SOIC package and commercial operating temperature range before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the SY100S834LZC when a 3.3V supply is required instead of the standard 5V variant. Choose this model over the industrial grade version if the application operates within the commercial temperature range. Verify that the required division ratios align with the FSEL configuration needs for the specific system architecture.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the SY100S834/L family, which includes variants supporting different voltage levels and temperature ranges. The 'L' suffix denotes the 3.3V operation capability, while 'ZC' indicates the 16-pin SOIC package and commercial temperature rating. It is distinct from the SY100S834ZI which offers industrial temperature support.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include SY100S834ZG for Pb-free compliance in industrial applications. For 5V operation requirements, consider the SY100S834ZC. Ensure any substitute maintains the same Z16-2 package footprint and logic level compatibility.
