5V41236PGG

Overview

The Renesas Electronics 5V41236PGG is a PCIe Gen1/Gen2/Gen3 compliant clock generator designed for communication and embedded systems. It features four differential HCSL outputs capable of reducing electromagnetic interference (EMI) through spread-spectrum functionality. The device operates with a 25 MHz crystal input and supports output frequencies up to 200 MHz. Key electrical parameters include a maximum jitter of 100 ps, an operating supply voltage of 3.3 V, and a current consumption of 115 mA. It is housed in a TSSOP-20 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• PCIe Gen1/Gen2/Gen3 compliant spread-spectrum clock generation
• Four differential HCSL outputs with <100 ps cycle-to-cycle jitter
• Hardware-selectable spread amount and frequency via pins
• Power-down pin for enhanced system power management

Applications

• PCI Express (PCIe) Gen1/Gen2/Gen3 systems
• Communication equipment requiring EMI reduction
• Embedded systems demanding low-jitter clock synthesis

Procurement Notes

Verify the specific suffix against the official datasheet to confirm package type and temperature grade. Confirm RoHS compliance status directly from the manufacturer's documentation before procurement. Ensure the ordering information matches the exact variant required for the design.

Selection Notes

Select this component when a PCIe-compliant synthesizer with four differential outputs is required. Verify that the 25 MHz input frequency aligns with the system reference clock. Check if the HCSL output signaling meets the load requirements of the destination devices compared to LVDS or LVPECL alternatives.

Part Context

The 5V41236 belongs to the 5V4123x family of PCIe clock generators. This series provides solutions for reducing EMI in high-speed digital designs. The PGG suffix typically denotes the TSSOP-20 package variant available in industrial temperature ranges.

Replacement Considerations

The 5V41236NLGI is listed as a discontinued alternative with a similar function but different packaging. Verify pinout compatibility and electrical specifications before substituting.
