5V41235PGGI8

Overview

The Renesas 5V41235PGGI8 is a PCIe Gen1/Gen2/Gen3 compliant spread spectrum clock generator designed to reduce electromagnetic interference (EMI) in communication and embedded systems. It features one PLL circuit with a maximum output frequency of 200MHz. The device accepts clock or crystal inputs and provides two differential HCSL outputs. It operates on a supply voltage ranging from 3.135V to 3.465V within an industrial temperature range of 0°C to 70°C. The component is housed in a 16-TSSOP package with a width of 4.40mm.

Feature Summary

• PCIe Gen1/Gen2/Gen3 compliant spread spectrum clock generation
• Two differential HCSL outputs for low noise signal distribution
• Spread amount and output frequency selectable via hardware select pins
• Supports 25 MHz, 125 MHz, and 200 MHz fixed outputs for Ethernet applications

Applications

• PCI Express (PCIe) system clock generation
• Ethernet interface timing solutions
• Embedded systems requiring EMI reduction
• Communication equipment clock synthesis

Procurement Notes

Verify the suffix 'I' indicates the industrial temperature grade (0°C to 70°C) and 'G8' denotes the tape and reel packaging format. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure the 16-TSSOP footprint matches the PCB layout requirements before procurement.

Selection Notes

Select this model when dual differential HCSL outputs are required for PCIe or Ethernet links. Compare against the 5V41235PGG variant if tube packaging is preferred over tape and reel. Verify input source compatibility, as the device supports both external clock signals and crystal oscillators.

Part Context

This component belongs to the 5V41235 family of FemtoClock clock generators. It serves as a specialized solution for high-speed serial interfaces like PCIe, offering spread spectrum capabilities to mitigate EMI issues common in dense electronic designs.

Replacement Considerations

The 5V41235PGG is a pin-compatible alternative available in tube packaging. Other models in the 5V41235 series may offer different output configurations or temperature ranges.
