23S05E-1DCG8

Overview

The Renesas 23S05E-1DCG8 is a clock buffer featuring spread spectrum technology, designed for 3.3V operation. It belongs to the 23S05-1HD series and utilizes an SOIC-8 surface-mount package. The component functions as a clock distribution device within the Clock & Timer ICs category. Official documentation identifies it as a specialized buffer intended for applications requiring frequency modulation capabilities to reduce electromagnetic interference.

Feature Summary

• Incorporates spread spectrum clocking functionality to manage signal integrity
• Operates at standard 3.3V supply voltage levels
• Provides dedicated clock buffering within a compact surface-mount form factor

Applications

• Clock distribution in high-speed digital systems
• Electromagnetic interference reduction in sensitive circuitry
• System timing architecture requiring spread spectrum modulation

Procurement Notes

Verify the specific suffix 'E' against official Renesas documentation to confirm exact electrical characteristics and revision status. Ensure compatibility with existing board layouts utilizing the SOIC-8 footprint. Cross-reference the part number with current manufacturer databases to validate active status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when spread spectrum clocking is required for noise mitigation rather than zero-delay buffering. Confirm that the operating frequency range aligns with system requirements. Evaluate the SOIC-8 package dimensions against PCB space constraints. Compare performance metrics against alternative buffers if jitter specifications are critical to the design.

Part Context

This part belongs to the Renesas 23S05 family of clock buffers. While related models like the 23S05-1H focus on low-skew zero-delay buffering, the 23S05E variant specifically integrates spread spectrum features. This distinction defines its role in managing electromagnetic emissions compared to standard distribution buffers in the same product line.

Replacement Considerations

Consult official substitution lists for direct equivalents. Verify pinout compatibility and electrical parameter alignment with any potential replacement parts from Renesas or other manufacturers.
