874003AGI-02LF

Overview

The 874003AGI-02LF is a PCI Express jitter attenuator manufactured by Renesas Electronics Corporation, belonging to the FemtoClock series. It functions as a differential-to-LVDS clock buffer with an integrated PLL for signal integrity enhancement. The device accepts one differential clock input supporting LVPECL, LVDS, LVHSTL, SSTL, or HCSL formats and provides three differential LVDS output pairs. Designed for space-constrained applications like add-in cards, it operates on a 3.3V supply within a -40°C to +85°C temperature range. The component utilizes 3rd Generation FemtoClock technology to minimize phase noise and supports PCI Express spread-spectrum clocking.

Feature Summary

• Three differential LVDS output pairs derived from a single differential clock input
• Integrated PLL with 3MHz loop bandwidth for effective jitter attenuation
• Supports multiple input standards: LVPECL, LVDS, LVHSTL, SSTL, and HCSL
• Compatible with PCI Express spread-spectrum clocking profiles

Applications

• PCI Express add-in cards in desktop PCs
• Systems requiring jitter reduction from low-bandwidth PLL synthesizers
• Space-constrained high-speed digital interfaces

Procurement Notes

The 874003AGI-02LF is listed as obsolete with no current stock availability. Verification of end-of-life status and final purchase orders should be conducted directly with Renesas Electronics or authorized distributors. Alternative components may be required for new designs due to the discontinued status of this specific part number.

Selection Notes

Select this component when designing PCI Express systems that require jitter attenuation from noisy source clocks. Ensure the input clock frequency falls within the supported range (98MHz to 128MHz) and the output frequency requirement (up to 320MHz). Verify compatibility with the 3.3V supply voltage and 20-TSSOP package constraints for the target PCB layout.

Part Context

This part belongs to the 874003DI-02 family, specifically the lead-free variant (suffix LF) in a tube carrier type. It is distinct from other FemtoClock devices by its specific 1:3 ratio and LVDS output configuration tailored for PCIe compliance.

Replacement Considerations

As the part is obsolete, consult Renesas documentation for officially confirmed substitute part numbers. Generic equivalents are not recommended without verifying electrical parameter alignment and pinout compatibility.
