5V41234NLG8

Overview

The IDT5V41234 is a single-output PCIe Gen1/Gen2/Gen3 compliant spread spectrum clock generator designed to reduce electromagnetic interference (EMI) in communication and embedded systems. It features one differential HCSL output with a frequency range of 100 MHz to 200 MHz, powered by a 3.3V supply. The device integrates a PLL for jitter cleaning and supports crystal inputs between 25 MHz and 25 MHz. Packaged in a compact 16-pin VFQFPN (3.0 x 3.0 mm) surface-mount format, it consumes approximately 231 mW of power and includes four differential termination resistors.

Feature Summary

• PCIe Gen1/Gen2/Gen3 Compliant: Supports high-speed serial interface standards with spread spectrum capability enabled via a select pin.
• Single Differential Output: Provides one HCSL output signal optimized for low noise and EMI reduction.
• Compact Packaging: Utilizes a 16-VFQFPN package with a small footprint of 9 mm² (3.0 x 3.0 mm).
• Integrated Termination: Includes built-in differential termination resistors to simplify board design.

Applications

• Communication Systems requiring low EMI clock sources.
• Embedded Systems needing compliant PCIe clock generation.
• High-Speed Data Acquisition equipment.

Procurement Notes

Verify the specific suffix 'G8' against the manufacturer's current datasheet to confirm package dimensions and lead finish specifications. Check for Product Change Notifications (PCNs) regarding assembly site changes or material updates. Ensure compatibility with the required 3.3V supply voltage and HCSL output signaling levels for the target application circuit.

Selection Notes

Select this component when a single differential HCSL output is sufficient for the design. Compare against the 5V41235 model if two outputs are required instead of one. Verify that the input crystal frequency matches the 25 MHz requirement. Confirm that the 100-200 MHz output frequency range meets the system timing requirements.

Part Context

This part belongs to the IDT 5V4123x family of PCIe clock synthesizers. It shares functional similarities with the 5V41235 but differs in output count. The device is manufactured by Renesas Electronics Corporation, having originated from Integrated Device Technology (IDT). It serves as a specialized timing solution for modern peripheral interfaces.

Replacement Considerations

The 5V41235NLG8 is a related variant offering two outputs instead of one. Direct substitution requires verifying if the additional output is necessary or if the single output of the 5V41234 is sufficient for the PCB layout constraints.
