5V41235NLGI8

Overview

The 5V41235NLGI8 is a PCIe Gen2/3 compliant spread spectrum clock generator manufactured by Renesas Electronics. It features two differential HCSL output pairs designed to reduce electromagnetic interference in communication and embedded systems. The device operates with a supply voltage of 3.135V to 3.465V and supports output frequencies of 25MHz, 100MHz, 125MHz, and 200MHz. Spread spectrum amount and frequency selection are configurable via hardware pins without software requirements. Key performance metrics include cycle-to-cycle jitter under 100ps and output-to-output skew under 50ps.

Feature Summary

• PCIe Gen2/3 compliant spread spectrum clock generation
• Two differential HCSL output pairs with LVDS termination capability
• Hardware-selectable spread percentage and output frequency
• Cycle-to-cycle jitter < 100 ps; Output-to-output skew < 50 ps

Applications

• PCI Express Gen2 and Gen3 system designs
• Ethernet applications requiring 25 MHz, 125 MHz, or 200 MHz outputs
• Embedded systems demanding EMI reduction

Procurement Notes

Verify the specific suffix 'I8' against the official datasheet to confirm package type and temperature range. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly planning. Check for Product Change Notifications regarding recent manufacturing site or labeling updates.

Selection Notes

Select this component when a fixed-frequency, hardware-configurable PCIe synthesizer is required. Ensure the design accommodates the 16-pin QFN package dimensions. Verify that the target application does not require programmable I2C/SPI configuration, as this model relies on pin-strapping for settings.

Part Context

This part belongs to the 5V41235 series of clock generators. It serves as a specialized solution for high-speed serial interfaces like PCIe, offering a compact footprint compared to larger packages while maintaining low jitter performance suitable for modern embedded standards.

Replacement Considerations

Direct substitutes within the same family include variants with different suffixes indicating package changes (e.g., TSSOP vs. QFN). Verify electrical compatibility if replacing with other 5V41235 models.
