853S011CGILFT

Overview

The 853S011CGILFT is a clock buffer manufactured by Renesas Electronics Corporation, belonging to the 853S011CI series. It functions as a 1:2 LVPECL/ECL fanout buffer designed for high-speed signal distribution. The device operates with a maximum frequency of 2.5 GHz and supports supply voltages ranging from 2.375 V to 3.8 V. It features a TSSOP-8 package suitable for surface mount applications. Key electrical parameters include a maximum propagation delay of 330 ps and a typical operating current of 24 mA. The component is rated for an ambient operating temperature range between -40°C and +85°C.

Feature Summary

• 1:2 differential-to-differential LVPECL/ECL fanout buffer configuration
• Maximum output frequency of 2.5 GHz
• Low propagation delay of 330 ps (maximum)
• Operates on a single supply voltage of 2.375 V to 3.8 V

Applications

• High-speed clock distribution networks
• Data communication systems requiring low skew timing
• Server and storage infrastructure clocking

Procurement Notes

Verify availability status carefully as this specific suffix variant may be discontinued or subject to replacement. Confirm the TSSOP-8 package type and RoHS compliance details against the latest manufacturer documentation before ordering. Check for official product change notices regarding assembly location changes or pin compatibility updates.

Selection Notes

Select this component when a 1:2 LVPECL fanout buffer with a TSSOP-8 footprint is required. Ensure the design accommodates the 2.375 V to 3.8 V supply range. Verify that the 330 ps maximum propagation delay meets system timing constraints. Consider the -40°C to +85°C industrial temperature rating for environmental suitability.

Part Context

This part is part of the 853S011BI/CI family of low skew clock buffers. It serves as a successor or alternative to earlier IDT/Renesas clock distribution products. The CGILFT suffix indicates a lead-free, halogen-free version in a TSSOP-8 tube package. It is distinct from the BMILFT variant which uses an SOIC-8 package.

Replacement Considerations

The datasheet lists the 8SLVP1102ANLGI as a possible replacement. Verify functional equivalence and pin compatibility before substitution.
