874005AGLF

Overview

The Renesas 874005AG-04LF is a FemtoClock PCI Express fanout buffer and jitter attenuator IC designed for high-speed digital interfaces. It features a single circuit with a 1:5 input-to-output ratio, supporting differential inputs and outputs. The device operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies up to 320MHz. It accepts various input formats including HCSL, LVDS, LVHSTL, LVPECL, and SSTL, while providing LVDS outputs. Packaged in a 24-TSSOP (0.173 inch width) surface-mount enclosure, it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• PCI Express compliant fanout buffer with integrated jitter attenuation capabilities
• 1:5 differential input to differential output configuration
• Supports multiple input standards: HCSL, LVDS, LVHSTL, LVPECL, and SSTL
• Operates at frequencies up to 320MHz with 3.3V nominal supply

Applications

• PCI Express clock distribution systems
• High-speed data communication equipment
• Server and storage backplane designs

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer, with the discontinuation notice dated March 1, 2019. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Designers should confirm RoHS3 compliance status and moisture sensitivity level (MSL 1) prior to procurement planning.

Selection Notes

Select this part for applications requiring low-jitter clock distribution for PCIe interfaces up to 320MHz. Ensure the design accommodates the 24-TSSOP package dimensions and the specific 3.135V–3.465V supply voltage requirements. Verify that the input signal format matches one of the supported standards (LVDS, LVPECL, etc.) and that the thermal environment stays within the 0°C to 70°C commercial grade range.

Part Context

The 874005AG-04LF belongs to the FemtoClock series from Renesas Electronics Corporation, formerly Intersil. This series specializes in precision clock generation and conditioning solutions for high-speed serial links. The '04' suffix typically denotes the specific pinout and output configuration variant within the 874005A family.

Replacement Considerations

Due to the EOL status, direct replacement parts are not explicitly confirmed in public documentation. Engineers must evaluate alternative FemtoClock devices or generic PCIe fanout buffers that match the 1:5 ratio, 320MHz speed, and 24-TSSOP package constraints.
