SY100EL14VZG

Clock Buffers, Drivers Overview

The SY100EL14VZG is a low-skew, 1:5 clock distribution chip designed for applications requiring precise timing. It supports differential or single-ended ECL and PECL inputs, operating with 3.3V to 5.0V supplies. The device features a multiplexed clock input for scan/test clock integration and a synchronous enable/disable function to prevent runt pulses. Key electrical parameters include a typical output-to-output skew of 30ps (max 50ps) and 70fs RMS additive phase jitter at 622MHz. Propagation delay ranges from 520ps to 830ps depending on temperature. It is housed in a 20-pin narrow SOIC package.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix when purchasing. The 'ZG' suffix indicates a lead-free, Pb-Free part with a NiPdAu finish in a tube package. Ensure compatibility with industrial temperature ranges (-40°C to +85°C). Confirm that the 20-pin SOIC footprint matches the design requirements before procurement.

Clock Buffers, Drivers Selection Notes

Select this component for systems requiring low-jitter clock distribution with multiplexing capabilities. It is suitable for both 3.3V and 5V supply environments. Consider the synchronous enable feature if runt pulse prevention is critical. Verify that the input signal swing meets the minimum VPP requirement of 150mV for proper operation.

Clock Buffers, Drivers Part Context

The SY100EL14VZG belongs to the SY100EL series of clock drivers. It was originally manufactured by Micrel, Inc., which has since been acquired by Microchip Technology. The datasheet revision 5.0 confirms the specifications and pinout configuration for this specific part number within the broader family of high-speed clock management ICs.

Clock Buffers, Drivers Replacement Considerations

Direct replacements should maintain 1:5 distribution, ECL/PECL compatibility, and similar skew/jitter specifications. Verify pinout compatibility and voltage levels. Consult official manufacturer cross-reference lists for confirmed equivalent parts.
