5V41236NLGI8

Overview

The 5V41236NLGI8 is a PCIe Gen1/2/3 compliant clock synthesizer manufactured by Renesas Electronics. It features four differential HCSL outputs and supports spread-spectrum capability to reduce electromagnetic interference (EMI). The device operates with a 25 MHz crystal input and generates output frequencies up to 200 MHz. Key electrical specifications include a cycle-to-cycle jitter of less than 100 ps and an output-to-output skew of less than 50 ps. It is designed for communication and embedded systems, offering power management via power-down and OE control pins.

Feature Summary

• PCIe Gen1/2/3 compliant spread-spectrum clock generator
• Four differential HCSL outputs with LVDS termination options
• Cycle-to-cycle jitter <100 ps; Output-to-output skew <50 ps
• Spread amount and frequency selectable via hardware pins

Applications

• PCI Express (PCIe) system clock generation
• Communication equipment timing
• Embedded systems requiring low EMI

Part Context

The 5V41236NLGI8 belongs to the 5V41236 family of clock generators. While the NLGI8 variant utilizes a QFN package, the PGGI variant uses a TSSOP-20 package. Both share similar functional characteristics as PCIe synthesizers. The NLGI8 package is distinct from the standard NLGI version which may have different packaging or status.
