9DML0451AKILF

Overview

The 9DML0451AKILF is a clock multiplexer from the Renesas 9DML04 family, designed for PCIe Gen 1–7 applications. It features two differential HCSL inputs and four differential LP-HCSL outputs with an operating frequency range of 1 MHz to 200 MHz. The device supports Common Clocked (CC), Separate Reference no Spread (SRnS), and Separate Reference Independent Spread (SRIS) architectures. It operates on a 3.3V supply voltage with typical power consumption of 76 mW. The component is housed in a space-saving 4mm x 4mm 24-VFQFPN package.

Feature Summary

• Supports PCIe Gen 1–7 CC, SRnS, and SRIS clocking architectures
• Selectable asynchronous or glitch-free switching modes
• Spread spectrum tolerant input capability
• Direct connection to 100Ω or 85Ω transmission lines

Applications

• PCI Express Gen 1–7 system designs
• Server and storage infrastructure clock distribution
• High-speed data acquisition systems requiring low jitter muxing

Part Context

The 9DML0451AKILF belongs to the 9DML04 series of 3.3V PCIe clock multiplexers. This family provides flexible clock routing solutions for high-speed serial interfaces, offering integrated termination options to reduce external component count compared to standard PCIe devices.
