874003AG-02LFT

Overview

The 874003AG-02LFT 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 high-performance clock distribution in PCIe systems. The device accepts a single differential clock input supporting LVPECL, LVDS, LVHSTL, SSTL, and HCSL formats. It provides three differential LVDS output pairs. Key electrical parameters include a maximum operating frequency of 320MHz, a supply voltage range of 3.135V to 3.465V, and a cycle-to-cycle jitter specification of 30ps maximum. It operates within an ambient temperature range of -40°C to 85°C and is housed in a 20-TSSOP package.

Feature Summary

• PCI Express Jitter Attenuator with 3MHz PLL loop bandwidth
• Supports Spread-Spectrum Clocking (SSC) profiles
• Input types: LVPECL, LVDS, LVHSTL, SSTL, HCSL
• Output: Three differential LVDS pairs

Applications

• PCI Express add-in cards
• Desktop PC motherboard clock distribution
• Systems requiring jitter attenuation from low-bandwidth PLL synthesizers

Procurement Notes

The 874003AG-02LFT is listed as obsolete or not recommended for new designs in public distributor records. Verification of current production status and availability through official Renesas channels is required before procurement planning. Alternative components within the FemtoClock family may be necessary for new implementations.

Selection Notes

Select this component for applications requiring jitter reduction on PCIe clocks up to 320MHz. Ensure the design supports the 3.3V nominal supply voltage and utilizes a 20-TSSOP footprint. Verify compatibility with the specific input clock format (LVPECL, LVDS, etc.) and confirm that the 30ps cycle-to-cycle jitter limit meets system requirements.

Part Context

This part is part of the IDT/Renesas FemtoClock family, originally developed by Integrated Device Technology (IDT) before its acquisition by Renesas. The 'AG' suffix typically denotes specific packaging or temperature grade variations within the 874003DI-02 product line. The 'LF' indicates lead-free compliance, and 'T' refers to tape-and-reel packaging.

Replacement Considerations

Public documentation lists the 874003I-02 as a related alternative within the same product family. Engineers should evaluate pinout compatibility and parameter equivalence when considering substitutes for this obsolete part number.
