553SDCGI

Overview

The Renesas 553SDCGI is a single-channel clock buffer and fan-out device designed for high-speed digital systems. It accepts one input signal and provides four buffered outputs, operating at frequencies up to 200 MHz. The component functions within a supply voltage range of 1.71 V to 3.465 V and supports surface-mount installation in an 8-SOIC package with a width of 3.90 mm. It exhibits a maximum propagation delay of 4 ns and operates reliably across an industrial temperature range from -40°C to +105°C.

Feature Summary

• Single-to-four channel fan-out buffering capability
• Maximum operating frequency of 200 MHz
• Supply voltage range of 1.71 V to 3.465 V
• Industrial temperature rating from -40°C to +105°C

Applications

• Clock distribution networks in embedded systems
• Fan-out buffering for high-speed digital interfaces
• System timing architecture in industrial equipment

Part Context

The 553SDCGI belongs to the Renesas 553S series of clock buffers. This family focuses on low-skew signal distribution for synchronous digital circuits. The specific model utilizes an 8-SOIC footprint, distinguishing it from other variants in the series that may use different packaging or pin configurations.

Replacement Considerations

Public documentation identifies the 551SDCGI as a parameter-equivalent substitute available from Renesas Electronics Corporation.
