74FCT3807SNDGI8

Overview

The 74FCT3807SNDGI8 is a low skew, single-input to ten-output LVCMOS clock buffer manufactured by Renesas Electronics. It belongs to the 74FCT3807 series and is designed for high-performance clock distribution applications requiring minimal phase jitter. The device operates within a supply voltage range of 1.8V to 3.3V and supports an operating temperature range from -40°C to +85°C. It features sub-50fs additive phase jitter performance, making it suitable for sensitive timing circuits. The component is supplied in a TSSOP package with 20 leads and a pitch of 0.65mm, optimized for surface-mount assembly.

Feature Summary

• Low skew architecture with sub-50fs additive phase jitter
• Single input to ten output configuration (1:10 fan-out)
• Wide supply voltage operation from 1.8V to 3.3V
• Extended industrial temperature range (-40°C to +85°C)

Applications

• High-speed data communication systems
• Server and storage clock distribution networks
• Telecommunications equipment timing circuits

Procurement Notes

Verify the specific suffix 'NDGI8' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the TSSOP-20 variant. Check current availability status as lead times may vary based on production cycles. Confirm RoHS compliance details through the manufacturer's datasheet before finalizing procurement orders.

Selection Notes

Select this component when low jitter performance is critical for clock distribution in mixed-voltage environments. The 1.8V to 3.3V operating range allows flexibility in system design. Compare electrical parameters such as propagation delay and output drive strength against alternative FCT family buffers. Ensure the 1:10 fan-out ratio meets the target circuit requirements without excessive loading.

Part Context

This part is part of the broader 74FCT3807 family of clock drivers. Variants within this family differ primarily in packaging options such as QSOP, SSOP, and TSSOP, as well as temperature ranges. The 'S' designation typically indicates the standard commercial or industrial grade version within the FCT line. Other suffixes denote specific package types and reel quantities.

Replacement Considerations

Direct replacements within the same family include other 74FCT3807 variants with different packages like 74FCT3807SQGI8 or 74FCT3807SPYGI8. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Consult Renesas recommended replacement lists for end-of-life scenarios.
