553SDCGI8

Overview

The Renesas Electronics 553SDCGI8 is a low skew clock buffer within the 553S series, designed for high-performance timing applications. It features a single input and four outputs, supporting maximum input frequencies up to 200 MHz. The device operates on a supply voltage range of 1.71 V to 3.465 V and exhibits a maximum propagation delay of 4 ns. Packaged in an 8-SOIC surface-mount format, it functions reliably across an extended temperature range from -40°C to +105°C. This component serves as a fan-out buffer to distribute clock signals with minimal jitter.

Feature Summary

• Four-output configuration with 1:4 fan-out ratio
• Maximum operating frequency of 200 MHz
• Low skew performance specified at 50 fs and 50 ps
• Wide supply voltage operation from 1.71 V to 3.465 V

Applications

• High-speed data communication systems requiring precise clock distribution
• Server and storage infrastructure timing networks
• Telecommunications equipment clock synchronization

Procurement Notes

Verify RoHS compliance status through official manufacturer documentation before integration. Confirm that the 8-SOIC package dimensions match the target PCB footprint. Ensure power supply rails remain within the 1.71 V to 3.465 V operational limits to maintain signal integrity and prevent device malfunction during long-term deployment.

Selection Notes

Select this component when a 1-to-4 clock distribution solution is required with specific low skew characteristics. Compare against the 551SDCGI8 if different propagation delay or series-specific features are needed. Verify that the 200 MHz frequency limit meets the system's maximum clock requirements and that the SOIC-8 package is compatible with available assembly equipment.

Part Context

This part belongs to the Renesas 553S family of clock buffers. It shares functional similarities with the 551SDCGI8 but may differ in internal specifications such as propagation delay or output drive strength. The 'GI8' suffix typically indicates the tape-and-reel packaging variant for automated surface-mount assembly processes.

Replacement Considerations

The 551SDCGI8 is listed as a parameter-equivalent alternative by distributors. Verify electrical compatibility, specifically checking for differences in propagation delay and skew specifications between the 553S and 551S series before substitution.
