853S024AYLF

Overview

The Renesas 853S024AYLF is a clock fanout buffer IC designed for high-frequency signal distribution. It features a 1:24 output ratio, supporting a maximum frequency of 1.5 GHz. The device accepts differential inputs compatible with HCSL, LVDS, LVHSTL, LVPECL, and SSTL standards, providing LVPECL outputs. It operates within a supply voltage range of 3.135V to 3.465V and functions at temperatures between 0°C and 70°C. The component is housed in a 64-TQFP package with exposed pads (10x10 mm) and is identified as end-of-life.

• Maximum operating frequency of 1.5 GHz
• Supports multiple input standards: HCSL, LVDS, LVHSTL, LVPECL, SSTL
• 64-TQFP package with exposed thermal pad

Applications

• High-speed data communication systems requiring clock distribution
• Telecommunications infrastructure equipment
• Industrial control systems utilizing precise timing signals

Procurement Notes

This component is officially listed as End of Life (EOL) by the manufacturer. Verification of availability should focus on distributor surplus stock or alternative qualified replacement parts. Ensure that any sourced units match the original RoHS-compliant lead-free specification and verify the specific manufacturing date code against current quality requirements.

Selection Notes

Select this part only if a 1:24 split ratio and 1.5 GHz capability are required. Verify that the system power supply strictly maintains the 3.135V–3.465V range. Confirm that the host board supports the 64-TQFP-EP footprint. Due to EOL status, evaluate pin-compatible or functionally equivalent successors from the same family for long-term production viability.

Part Context

The 853S024AYLF belongs to the 853S series of low-skew clock buffers. It serves as a distribution amplifier for differential clock signals in complex digital systems. The 'A' suffix typically denotes temperature grade, while 'YLF' indicates the specific tape-and-reel packaging and lead-free material composition defined by the manufacturer's ordering nomenclature.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users must consult the manufacturer's official obsolescence notice or contact sales engineering for validated cross-reference recommendations.
