5V41065PGGI

Overview

The 5V41065PGGI is a PCIe Gen2 compliant clock generator manufactured by Renesas Electronics. It features two differential HCSL outputs and supports spread-spectrum capabilities to reduce electromagnetic interference (EMI). The device accepts a 25 MHz input frequency and generates output frequencies of 25 MHz, 125 MHz, or 200 MHz via hardware pin selection. Key electrical parameters include a maximum output frequency of 200 MHz, a cycle-to-cycle jitter of less than 100 ps, and an output-to-output skew of less than 50 ps. It operates on a 3.3 V supply with a typical current consumption of 63 mA within the -40°C to +85°C industrial temperature range.

Feature Summary

• PCIe Gen2 compliant spread-spectrum clock generation for EMI reduction
• Two differential HCSL output pairs with selectable termination
• Hardware-configurable output frequencies: 25 MHz, 125 MHz, and 200 MHz
• Low jitter performance: <100 ps cycle-to-cycle and <50 ps output-to-output skew

Applications

• PCI Express Gen2 system clock distribution
• Ethernet applications requiring 25 MHz, 125 MHz, or 200 MHz references
• Embedded systems demanding low EMI signatures
• Communication infrastructure equipment

Procurement Notes

Verify the specific suffix 'PGGI' corresponds to the TSSOP-16 package and industrial temperature grade (-40°C to +85°C) in official Renesas documentation. Confirm RoHS compliance status through the manufacturer's datasheet or environmental files, as packaging variations may exist. Cross-reference the Mouser part number 972-5V41065PGGI for accurate sourcing channels.

Selection Notes

Select this component when a dual-output HCSL clock source with integrated spread-spectrum functionality is required for PCIe Gen2 designs. Ensure the design utilizes hardware pin selection for frequency configuration rather than software I2C control. Verify that the 25 MHz crystal input matches the system oscillator requirements and that the 3.3 V power rail aligns with the target logic levels.

Part Context

This part belongs to the 5V41065 series of clock generators designed for high-speed serial interface applications. It serves as a direct replacement for legacy synthesizers in PCIe Gen1/Gen2 architectures. The device integrates PLL circuitry and voltage-controlled oscillators into a compact 16-pin TSSOP or VFQFPN footprint, optimizing board space compared to discrete solutions.
