5V41236NLG

Overview

The Renesas 5V41236NLG is a PCIe Gen1/2/3 compliant clock generator designed for embedded systems and communication applications. It features four differential HCSL outputs capable of generating frequencies up to 200 MHz from a 25 MHz crystal input. The device supports spread-spectrum functionality to reduce electromagnetic interference (EMI), with jitter performance below 100 ps cycle-to-cycle. It operates on a single 3.3 V supply within an industrial temperature range of -40°C to +85°C, housed in a compact 20-lead VFQFPN package.

Feature Summary

• Four differential HCSL outputs supporting PCIe Gen1/2/3 standards
• Spread-spectrum capability selectable via hardware pins without software configuration
• Low jitter performance: <100 ps cycle-to-cycle and <1.0 ps RMS phase jitter for PCIe Gen3
• Compact 20-VFQFPN (4x4 mm) surface-mount package

Applications

• PCI Express (PCIe) compliant system designs
• Embedded systems requiring low EMI solutions
• Communication infrastructure equipment

Part Context

The 5V41236NLG belongs to the 5V41236 family of clock synthesizers. While the NLG suffix denotes the specific 20-VFQFPN package variant, the PGGI variant offers the same electrical specifications in a TSSOP-20 package. Both variants share identical functional capabilities regarding output signaling and jitter performance.

Replacement Considerations

The 5V41236PGGI is a verified alternative offering identical electrical characteristics but utilizes a TSSOP-20 package instead of the VFQFPN form factor. Designers must verify footprint compatibility when substituting between these package types.
