5V41235NLGI

Overview

The 5V41235NLGI is a PCIe Gen1/2/3 compliant spread spectrum clock generator manufactured by Renesas Electronics. It features two differential HCSL outputs designed to reduce electromagnetic interference in communication and embedded systems. The device operates within a supply voltage range of 3.135V to 3.465V and supports output frequencies up to 200MHz. It utilizes a 16-VFQFPN (3x3) surface-mount package with an exposed pad. The component includes an internal PLL and accepts clock or crystal inputs, functioning as a dedicated timing solution for high-speed serial interfaces.

Feature Summary

• PCIe Gen1/2/3 Compliant Spread Spectrum Clock Generation

• Internal PLL with Input Options for Clock or Crystal
• 16-VFQFPN Package with Exposed Pad

Applications

• PCI Express System Clocking
• Communication Equipment Timing
• Embedded Systems Interconnects

Procurement Notes

Verify the specific suffix 'I8' against the requested model '5V41235NLGI', as distributor data indicates '5V41235NLGI8' as the standard reel-packaged variant. Confirm moisture sensitivity level (MSL 3) and reflow soldering profile requirements prior to assembly. Check current stock availability as supply may be limited or subject to factory order constraints.

Selection Notes

Select this component when designing for PCIe Gen1 through Gen3 interfaces requiring spread spectrum capabilities to minimize EMI. Ensure the design accommodates the 16-VFQFPN footprint and thermal pad requirements. Verify that the system power supply provides the specified 3.135V to 3.465V range and that the input source matches the device's clock or crystal input specifications.

Part Context

The 5V41235 belongs to the VersaClock family of clock generators from Renesas. It is part of a series including variants like the 5V41235PGG and 5V41235NLG8, which share similar functional cores but differ in package type and packaging format. This specific model targets applications needing compact form factors with integrated spread spectrum functionality.

Replacement Considerations

The 5V41235NLG8 is a functionally equivalent alternative available in the same 16-VFQFPN package. Verify pinout compatibility and electrical parameters before substitution. Other family members like the 5V41235PGG offer different packaging options but require mechanical redesign.
