621SCMGI8

Overview

The 621SCMGI8 is a clock buffer integrated circuit manufactured by Renesas Electronics Corporation, belonging to the 621S series. It functions as a single-input, four-output fan-out buffer designed for low-skew clock distribution. The device supports a maximum operating frequency of 200 MHz and operates within a supply voltage range of 1.71 V to 3.465 V. It is housed in an 8-UFDFN package with dimensions of 2x2 mm. The component is rated for an ambient operating temperature range from -40°C to +105°C and complies with RoHS3 specifications.

Feature Summary

• Single-to-four output configuration (1:4 ratio) for clock signal distribution
• Maximum operating frequency of 200 MHz
• Low skew performance suitable for precision timing applications
• Operates on a single supply voltage between 1.71 V and 3.465 V

Applications

• High-speed digital systems requiring precise clock synchronization
• Data communication equipment utilizing LVCMOS outputs
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify the specific suffix 'CGI8' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm current production status and lead times directly with authorized distributors, as availability may vary. Ensure compliance with RoHS3 requirements if applicable to the target assembly process.

Selection Notes

Select this component when a 1:4 clock fan-out buffer is required with a maximum frequency of 200 MHz. The 8-VFQFN (2x2) package is suitable for space-constrained surface-mount designs. Verify that the system power supply falls within the 1.71 V to 3.465 V range and that the operating environment stays within -40°C to +105°C.

Part Context

The 621SCMGI8 is part of the Renesas 621S family of clock buffers. This series provides low-skew solutions for distributing reference clocks to multiple components. The 'S' variant typically denotes specific electrical characteristics and packaging options distinct from other members like the 621NLFT or 621SDCGI8.

Replacement Considerations

The 621NLFT is identified as a discontinued alternative within the same product family. Verify pin compatibility and electrical parameters before substituting. No other direct public substitutes are confirmed in the provided data.
