5V41234NLGI8

Overview

The 5V41234NLGI8 is a PCIe Gen2/3 compliant spread spectrum clock generator manufactured by Renesas Electronics. It features one differential HCSL output and operates with a fixed crystal frequency of 25 MHz. The device supports an output frequency range of 100 to 100 MHz, consuming approximately 231 mW at a 3.3 V supply voltage. Packaged in a 16-lead VFQFPN (3.0 x 3.0 mm) surface-mount housing, it includes four differential termination resistors. Spread spectrum functionality can be enabled via a dedicated select pin to reduce electromagnetic interference.

Feature Summary

• PCIe Gen2/3 Compliant: Designed for communication and embedded systems requiring low EMI.
• Spread Spectrum Capability: Reduces electromagnetic interference when enabled via a select pin.
• Single Differential Output: Provides one HCSL differential output signal.
• Fixed Crystal Input: Operates with a 25 MHz crystal frequency.

Applications

• Communication Systems
• Embedded Systems
• PCI Express Interfaces

Procurement Notes

Verify the specific suffix 'I8' against the official datasheet to confirm package type and temperature range. Factory packaging quantity is typically 2500 units per reel. Confirm moisture sensitivity level (MSL 3) requirements for storage and handling prior to assembly.

Selection Notes

Select this component for designs requiring a single differential HCSL output with spread spectrum capabilities. Ensure the design accommodates the 25 MHz crystal input and the 3.3 V power supply. Verify that the 16-VFQFPN package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the IDT 5V4123x series of PCIe clock synthesizers. It is functionally similar to the 5V41235 but differs in output configuration or feature set. The product line is designed to support high-speed serial interface standards with jitter cleaning and EMI reduction.

Replacement Considerations

The 5V41235NLGI8 is a related part within the same family. Verify if the alternative meets the specific output count and frequency requirements. Check for any changes in package dimensions or electrical characteristics before substitution.
