874003BG-05LFT

Overview

The Renesas 874003BG-05LFT is a PCI Express jitter attenuator IC designed for high-performance differential-to-LVDS signal conditioning. It features a 1:3 input-to-output ratio with a single HCSL or LVDS differential input and three LVDS outputs. The device operates at a maximum frequency of 320 MHz with a bandwidth of 6.2 MHz, ensuring less than 1 dB peaking to meet PCIe Gen2 PLL requirements. It utilizes Spread Spectrum technology and is housed in a 20-TSSOP surface-mount package.

Feature Summary

• Differential-to-LVDS jitter attenuation optimized for PCI Express systems
• Spread spectrum functionality for EMI reduction
• Single differential input driving three LVDS outputs
• Compliance with PCI Express Gen1 and Gen2 jitter specifications

Applications

• PCI Express Gen1 and Gen2 clock distribution networks
• High-speed digital interface jitter cleaning
• Server and storage system clock generation
• Network infrastructure equipment requiring low-jitter signals

Procurement Notes

Verify component status as the 874003BG-05LFT is listed as obsolete. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing PCB footprints and design-in requirements before procurement. Check for valid RoHS compliance documentation given the lead-free designation.

Selection Notes

Select this component when designing for PCI Express Gen1 or Gen2 interfaces requiring precise jitter attenuation. The 1:3 fanout capability suits applications needing multiple synchronized LVDS clocks from a single source. Consider the 20-TSSOP package constraints and thermal performance. Evaluate if the 6.2 MHz bandwidth aligns with specific PLL loop filter requirements.
