651SCMGI

Overview

The Renesas 651SCMGI is a single-input to four-output LVCMOS clock buffer IC designed for low skew applications. It operates within a supply voltage range of 1.71V to 3.465V, supporting three distinct voltage domains: 1.8V (1.71V–1.89V), 2.5V (2.375V–2.625V), and 3.3V (3.135V–3.465V). The device supports maximum input frequencies up to 200 MHz with a maximum propagation delay of 4.5 ns. It is housed in an 8-UFDFN package (8-VFQFN, 2x2 mm) and functions across an operating temperature range of -40°C to 105°C.

Feature Summary

• Single-to-four output LVCMOS clock buffering configuration
• Maximum operating frequency of 200 MHz
• Triple voltage support: 1.8V, 2.5V, and 3.3V domains
• 8-pin UFDFN surface-mount package

Applications

• Clock distribution networks requiring low skew performance
• Systems utilizing LVCMOS logic interfaces
• Multi-voltage domain timing synchronization

Procurement Notes

Verify the specific suffix against the manufacturer's current documentation, as the '651SCMGI' designation may correspond to tube or reel packaging variants. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the selected variant matches the required packaging quantity and moisture sensitivity level specifications for the intended assembly process.

Selection Notes

Select this component when a single-ended LVCMOS input must drive four separate loads with minimal skew. Verify that the system power rails align with the specified 1.8V, 2.5V, or 3.3V operating ranges. Ensure the PCB layout accommodates the 2x2 mm 8-VFQFN footprint and that thermal requirements are met within the -40°C to 105°C ambient temperature range.

Part Context

This part belongs to the 651S series of clock buffers. It serves as a foundational component for timing distribution in digital systems. Related variants include the 651SCMGI8, which shares identical electrical characteristics but differs in standard shipping packaging (reel vs. tube/other).

Replacement Considerations

The 651SCMGI8 is a parameter-equivalent alternative from Renesas Electronics Corporation. It offers identical electrical specifications and pinout compatibility, differing primarily in packaging format.
