651SDCGI8

Overview

The 651SDCGI8 is a low skew clock buffer manufactured by Renesas Electronics, belonging to the 621S series. It features one input and four outputs with LVCMOS logic levels. The device supports a maximum input frequency of 200 MHz and exhibits a maximum propagation delay of 4.5 ns. It operates within a supply voltage range of 1.71 V to 3.465 V and functions reliably across an industrial temperature range from -40°C to +105°C. The component is designed for surface mount installation in compact electronic applications requiring precise timing distribution.

Feature Summary

• Four LVCMOS outputs driven by a single input
• Low skew performance specified at 50fs RMS
• Maximum operating frequency of 200 MHz
• Wide supply voltage compatibility from 1.71 V to 3.465 V

Applications

• Clock distribution networks in high-speed digital systems
• Timing synchronization for data converters and memory interfaces
• Signal buffering in telecommunications equipment

Procurement Notes

Verify the specific package variant and tape-and-reel quantity against the official datasheet before ordering. Confirm that the supply voltage requirements align with the target circuit design. Check for any recent Product Change Notifications (PCN) regarding marking or material updates. Ensure the procurement channel provides valid RoHS compliance documentation. Validate the lead time estimates directly with the manufacturer or authorized distributor.

Selection Notes

Select this component when a 1-to-4 fan-out configuration with LVCMOS outputs is required. Ensure the system power supply falls within the 1.71 V to 3.465 V operational window. Verify that the 200 MHz maximum frequency meets the signal requirements. Consider the -40°C to +105°C temperature rating for environmental suitability. Compare propagation delay specifications if tighter timing constraints exist.

Part Context

This part belongs to the Renesas 621S family of clock buffers. It shares functional similarities with other models in the series but is distinguished by its specific output count and electrical characteristics. The suffix 'GI8' typically denotes the package type and reel packaging configuration used for surface mount assembly.

Replacement Considerations

Direct substitutes within the same family include the 651SCMGI and 651SCMGI8. These alternatives offer similar 1-to-4 buffering capabilities. Verify pinout compatibility and package dimensions before swapping components in an existing design.
