5V41065NLG

Overview

The 5V41065NLG is a PCIe Gen2 compliant clock generator manufactured by Renesas Electronics. It features two differential HCSL output pairs designed to reduce electromagnetic interference (EMI) in communication and embedded systems. The device supports selectable spread-spectrum capabilities via hardware pins, eliminating the need for software configuration. It operates with a single 3.3V supply and accepts a 25 MHz input frequency. Key electrical parameters include a maximum output frequency of 200 MHz, cycle-to-cycle jitter less than 100 ps, and an operating temperature range from -40°C to +85°C.

Feature Summary

• PCIe Gen2 compliant spread spectrum clock generator
• Two differential HCSL output pairs
• Hardware-selectable spread percentage and frequency
• Cycle-to-cycle jitter < 100 ps

Applications

• PCI Express Gen2 systems
• Communication equipment
• Embedded systems requiring EMI reduction

Procurement Notes

Verify the package type against project requirements, as the 5V41065 series is available in both TSSOP-16 and VFQFPN-16 configurations. Confirm that the specific suffix 'NLG' corresponds to the desired package variant and lead-free status. Cross-reference the manufacturer's latest datasheet to ensure the component meets current RoHS directives and environmental compliance standards before procurement.

Selection Notes

Select this component when a low-pin-count solution is required for PCIe Gen2 applications. The 5V41065 offers a smaller board footprint compared to higher-output variants like the 5V41066. Ensure the design utilizes the hardware pin-strapping method for frequency and spread-spectrum configuration, as the device lacks I2C programmability. Verify that the load capacitance matches the HCSL output specifications for optimal signal integrity.

Part Context

The 5V41065 belongs to the Renesas 5V4106x family of clock generators. It serves as a lower-output alternative to the 5V41066, which provides four outputs. Both devices share similar core functionalities, including PCIe Gen2 compliance and spread-spectrum capabilities. The 5V41065 is distinct from the 5V41285, which is a clock synthesizer/jitter cleaner rather than a generator.

Replacement Considerations

The IDT5V41065PGGI is listed as an alias for this part number. Direct replacement requires verifying that the package type (TSSOP vs. VFQFPN) and pinout are identical. Other family members like the 5V41066 offer more outputs but may require different PCB layout considerations.
