853S011CGILF

Overview

The 853S011CGILF is a clock fanout buffer manufactured by Renesas Electronics Corporation. It functions as a 1-to-2 differential-to-LVPECL/ECL multiplexer and translator, accepting CML, LVDS, LVPECL, or SSTL inputs to drive two LVPECL or ECL outputs. The device operates within a supply voltage range of 2.375 V to 3.8 V and supports maximum frequencies up to 2.5 GHz. It features a maximum propagation delay of 330 ps and operates at a typical working current of 24 mA. The component is housed in an 8-TSSOP package with dimensions suitable for surface-mount technology.

Feature Summary

• 1:2 Differential Fanout Buffer supporting LVPECL and ECL output formats
• Maximum operating frequency of 2.5 GHz with 330 ps max propagation delay
• Wide supply voltage range from 2.375 V to 3.8 V
• Operational temperature range spanning -40°C to +85°C

Applications

• High-speed clock distribution networks requiring differential translation
• System boards with space constraints utilizing compact TSSOP packaging
• Data communication equipment requiring low skew signal buffering

Procurement Notes

This specific part number (853S011CGILF) is listed as discontinued or obsolete by the manufacturer. Verification of availability should focus on surplus distributors or potential replacement components such as the 8SLVP1102ANLGI. Buyers must confirm end-of-life status and lead times through authorized channels before procurement planning.

Selection Notes

Designers should verify that the 8-TSSOP package meets board layout requirements, noting the 0.65 mm pitch. Since the input accepts multiple logic levels (CML, LVDS, LVPECL), ensure external termination resistors match the selected input standard. The 24 mA operating current must be accounted for in thermal management calculations for dense PCB assemblies.

Part Context

The 853S011CGILF belongs to the 853S011CI series of clock buffers. It shares functional similarities with other variants like the 853S011BMILFT but differs in package type (TSSOP vs SOIC) and specific suffix designations indicating manufacturing lot or revision details. It serves as a specialized component for translating and distributing high-frequency differential clock signals.

Replacement Considerations

Public records indicate the 8SLVP1102ANLGI as a potential replacement candidate for this discontinued part. Engineers should compare pin compatibility and electrical specifications against the original datasheet before substitution.
