74FCT38074SCMGI

Overview

The 74FCT38074SCMGI is a low skew, single input to four output LVCMOS clock buffer manufactured by Renesas Electronics. It features best-in-class additive phase jitter of sub 50fs RMS. The device operates within a supply voltage range of 1.8V to 3.3V and supports maximum input frequencies up to 200 MHz. Propagation delay is typically 4.5 ns. It is housed in an 8-pin VQFN package with dimensions of 3.0mm x 3.0mm.

Feature Summary

• Low skew clock buffer with 1 input and 4 outputs
• Sub 50fs RMS additive phase jitter performance
• Wide supply voltage operation from 1.8V to 3.3V
• Maximum operating frequency of 200 MHz

Applications

• High-speed data acquisition systems
• Telecommunications equipment requiring precise clock distribution
• Test and measurement instruments
• Networking infrastructure components

Procurement Notes

Verify the specific suffix 'SCMGI' corresponds to the 8-pin VQFN package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the component meets the required thermal specifications for the intended application environment.

Selection Notes

Select this component for applications requiring minimal clock skew and ultra-low jitter across multiple outputs. Compare against other members of the 74FCT3807x family if different output counts (e.g., 1-to-2 or 1-to-5) are needed. Verify that the 1.8V to 3.3V operating range aligns with the system power rails.

Part Context

This part belongs to the 74FCT3807x series of low skew clock buffers. It shares core jitter performance characteristics with siblings like the 74FCT3807S and 74FCT38074S but differs in pin count and package configuration. The 'SCMGI' suffix specifically denotes the VQFN package option.

Replacement Considerations

Direct replacements include other variants within the 74FCT3807x family such as the 74FCT38074S in alternative packages. Cross-reference pinouts and electrical parameters carefully when substituting with devices from other manufacturers offering similar low-skew LVCMOS buffers.
