874005AG-04LF

Overview

The Renesas 874005AG-04LF is a PCI Express (PCIe) fanout buffer and jitter attenuator IC from the FemtoClock series. It features a single circuit with a 1:5 input-to-output ratio, designed to distribute clock signals in high-speed digital systems. The device accepts differential inputs via HCSL, LVDS, LVHSTL, LVPECL, or SSTL formats and provides differential LVDS outputs. Operating at a maximum frequency of 320MHz, it requires a supply voltage between 3.135V and 3.465V. Packaged in a 24-TSSOP housing, it supports surface-mount installation and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrated PLL-based jitter attenuation for PCIe applications
• 1:5 fanout ratio with differential input and output support
• Multi-standard input compatibility including LVDS, LVPECL, and HCSL
• Maximum operating frequency of 320MHz

Applications

• PCI Express clock distribution networks
• High-speed data communication systems requiring low-jitter clocking
• Server and storage infrastructure timing solutions

Procurement Notes

This component is officially listed as End-of-Life (EOL) by Renesas Electronics Corporation, with the discontinuation effective March 1, 2019. Verification of current availability should focus on surplus distributors or last-time-buy status rather than direct manufacturer production. Confirm RoHS3 compliance and moisture sensitivity level (MSL 1) when sourcing from secondary markets.

Selection Notes

Select this part for designs requiring a fixed 1:5 PCIe clock fanout with integrated jitter cleaning. Ensure the system power supply strictly maintains the 3.135V to 3.465V range. Verify that the input signal format matches one of the supported standards (LVDS, LVPECL, etc.). Due to the EOL status, alternative components with similar pinouts and electrical specifications must be evaluated for new designs.

Part Context

The 874005AG-04LF belongs to the FemtoClock family of precision clock generators and buffers. This series is engineered for noise reduction and signal integrity in high-frequency applications. The '04' suffix typically denotes specific packaging and pin configuration variants within the 874005A product line, tailored for TSSOP mounting.

Replacement Considerations

As the part is discontinued, verify functional equivalents from Renesas or other manufacturers offering PCIe fanout buffers with 1:5 ratios and 320MHz+ performance. Check for pin-compatible alternatives in 24-TSSOP packages to minimize PCB redesign efforts.
