874003AGLFT

Overview

The Renesas 874003AGLFT is a PCI Express jitter attenuator and distribution buffer belonging to the FemtoClock series. It features an integrated PLL for clock conditioning, supporting input formats including LVPECL, LVDS, LVHSTL, SSTL, and HCSL. The device provides one differential input and three differential LVDS outputs with a 1:3 ratio. Operating at frequencies up to 160MHz, it requires a supply voltage of 3.135V to 3.465V. Packaged in a 20-TSSOP surface-mount housing, this component is designed for space-constrained applications such as PCIe add-in cards.

Feature Summary

• PCI Express Jitter Attenuator with 1:3 Input-to-Output Ratio
• Supports LVPECL, LVDS, LVHSTL, SSTL, and HCSL Differential Inputs
• Generates Three Differential LVDS Outputs
• Maximum Frequency of 160MHz with Integrated PLL

Applications

• PCI Express Add-in Cards
• Desktop PC Systems
• Space-Constrained Electronic Designs

Procurement Notes

The 874003AGLFT is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus distributors or alternative packaging types such as tape and reel (TR), which may be available despite the original tube packaging being discontinued. Confirm RoHS3 compliance status during sourcing.

Selection Notes

Select this component when designing systems requiring jitter attenuation for PCI Express clocks generated by low-bandwidth synthesizers. Ensure the design accommodates the specific 3.135V to 3.465V supply range and the 20-TSSOP footprint. Verify that the required output format matches the differential LVDS specification provided by the device.
