874003AGI-02LFT

Overview

The 874003AGI-02LFT is a PCI Express jitter attenuator manufactured by Renesas Electronics Corporation. It operates with a maximum frequency of 320MHz and utilizes a 1:3 input-to-output ratio. The device features differential LVDS outputs and accepts various input types including LVPECL, LVDS, LVHSTL, SSTL, and HCSL. It functions within a supply voltage range of 3.135V to 3.465V and supports an ambient operating temperature from -40°C to +85°C. Packaged in a 20-TSSOP format, this component is designed for high-performance clock distribution in space-constrained applications.

Feature Summary

• PCI Express jitter attenuation with 3MHz PLL loop bandwidth
• Three differential LVDS output pairs
• Supports PCI Express Spread-Spectrum Clocking
• Cycle-to-cycle jitter specification of 30ps (maximum)

Applications

• PCI Express add-in cards
• Desktop PC systems requiring jitter reduction
• Clock distribution networks

Procurement Notes

Verify the specific suffix 'AGI' against official documentation, as standard listings often reference 'DGI'. Confirm current status as obsolete or last-time-buy through authorized channels. Ensure RoHS compliance matches project requirements. Check for moisture sensitivity level constraints during storage and handling.

Selection Notes

Select this component when low phase noise and jitter attenuation are critical for PCIe signal integrity. The 3MHz bandwidth effectively tracks spread-spectrum profiles while filtering high-frequency noise. Ensure the design accommodates the 20-TSSOP package dimensions and thermal characteristics for the target application environment.
