5V41234NLGI

Overview

The IDT5V41234NLGI is a single-output PCIe Gen2/3 compliant spread spectrum clock generator manufactured by Renesas Electronics. Designed for communication and embedded systems, it features one differential HCSL output to reduce electromagnetic interference (EMI). The device operates with a fixed 25 MHz crystal input frequency and supports an output frequency range of 100 MHz to 100 MHz. It functions within a supply voltage of 3.3 V and consumes approximately 231 mW of power. The component is housed in a compact 16-lead VFQFPN package measuring 3.0 x 3.0 mm.

Feature Summary

• PCIe Gen2/3 Compliant: Supports high-speed serial interface standards for modern computing applications.
• Spread Spectrum Capability: Reduces EMI through selectable spread spectrum modulation enabled via a dedicated select pin.
• Differential HCSL Output: Provides one differential output signaling compatible with High-Speed Current-Mode Logic loads.
• Compact Packaging: Utilizes a 16-lead VFQFPN package with a small footprint of 9 mm².

Applications

• Communication Systems
• Embedded Systems
• PCI Express Peripheral Devices

Procurement Notes

Verify the current lifecycle status of the 5V41234NLGI before procurement, as clock generator components frequently undergo obsolescence notices. Confirm that the specific suffix NLGI corresponds to the required 16-lead VFQFPN package variant. Ensure compatibility with the 25 MHz reference crystal requirement specified in the datasheet. Check for available replacement part numbers if the primary component is discontinued.

Selection Notes

Select this component when a single differential HCSL output is required for PCIe Gen2 or Gen3 interfaces. Verify that the system design accommodates the fixed 25 MHz crystal input frequency. Consider the 231 mW typical power consumption for thermal management in dense embedded layouts. Ensure the application benefits from spread spectrum capabilities for EMI reduction requirements.

Part Context

The 5V41234 belongs to the IDT/Renesas 5V41xxx series of PCIe clock synthesizers. This family provides compliant clock solutions for high-speed serial buses. The NLGI suffix denotes the specific 16-lead VFQFPN package configuration used in space-constrained designs.

Replacement Considerations

Consult the manufacturer's official substitution guide for verified replacements. Alternative parts must support PCIe Gen2/3 compliance, HCSL differential outputs, and 25 MHz crystal inputs. Verify package compatibility if substituting with different lead counts or dimensions.
