853S202AYILF

Overview

The Renesas 853S202AYILF is a high-performance clock fanout buffer manufactured by Renesas Electronics Corporation. It features a 1:24 output ratio, supporting up to 1.5 GHz maximum frequency. The device accepts differential inputs including LVPECL, LVDS, HCSL, LVHSTL, and SSTL, while providing LVPECL outputs. It operates on a single 3.135V to 3.465V supply voltage within an ambient temperature range of 0°C to 70°C. The component is housed in a 64-TQFP package with exposed pad (10x10 mm) for surface mount installation.

Procurement Notes

Verify the specific suffix 'AYILF' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Confirm current availability as this series may have obsolescence notices or alternative replacements available from the manufacturer.

Selection Notes

Select this component when a single differential clock source requires distribution to twenty-four LVPECL loads. Ensure the input signal matches one of the supported formats (LVPECL, LVDS, etc.) and that the system power supply aligns with the 3.135V-3.465V requirement. Verify thermal management capabilities for the 64-TQFP package.

Part Context

This part belongs to the Renesas 853S family of low-skew clock buffers. It serves as a critical timing element in complex digital systems requiring precise clock synchronization across multiple receivers. The 853S202 variant specifically provides a high fanout ratio suitable for distributing reference clocks to numerous FPGA or ASIC inputs.

Replacement Considerations

Consult Renesas datasheets for direct pin-compatible substitutes within the 853S series, such as the 853S024 or 853S12, depending on required fanout ratios. Verify electrical compatibility before substitution.
