874003AG-02LF

Overview

The 874003AG-02LF is a PCI Express jitter attenuator from the FemtoClock series, manufactured by Renesas Electronics Corporation. It functions as a differential-to-LVDS clock buffer with an integrated Phase-Locked Loop (PLL). The device accepts HCSL, LVDS, LVHSTL, LVPECL, or SSTL inputs and provides three differential LVDS outputs. 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. Key electrical parameters include a maximum frequency of 320MHz and a cycle-to-cycle jitter specification of 30ps maximum.

Feature Summary

• Supports PCI Express Spread-Spectrum Clocking
• 3MHz PLL loop bandwidth for effective jitter attenuation
• Low phase noise using 3rd Generation FemtoClock technology
• Available in a 20-TSSOP package

Applications

• PCI Express add-in cards
• Desktop PC systems requiring jitter reduction
• Space-constrained high-speed digital designs

Procurement Notes

Verify component status prior to procurement as this part number may be obsolete or discontinued. Confirm lead-free (RoHS 6) compliance and package type (20-TSSOP) against current manufacturer documentation. Check for valid replacement options if active sourcing is required.

Selection Notes

Select this component when designing PCI Express interfaces that require jitter attenuation from low-bandwidth PLL synthesizers. Ensure input signal compatibility with supported standards such as HCSL or LVPECL. Verify that the 320MHz maximum frequency meets system requirements and that the 20-TSSOP package fits the PCB layout constraints.

Part Context

This component belongs to the FemtoClock family of clock generators and buffers. It is designed to replace standard clock drivers in high-speed serial link applications where signal integrity is critical. The device integrates PLL technology to clean up noisy clock signals generated by system synthesizers.

Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Generic substitutes may not match the specific 3MHz loop bandwidth or jitter performance characteristics required for PCI Express compliance.
