9DMV0131BKILFT

Overview

The 9DMV0131BKILFT is a clock multiplexer IC from Renesas Electronics Corporation, designed for PCI Express (PCIe) applications. It features a 2:1 input-to-output ratio with differential HCSL inputs and differential LP-HCSL outputs. The device operates at a maximum frequency of 167 MHz and supports spread spectrum clocking for EMI reduction. It functions within a supply voltage range of 1.425 V to 1.575 V and is housed in a 16-VFQFPN package with exposed pad. The component is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• 2:1 Multiplexing Ratio: Selects between two differential HCSL inputs to drive a single differential LP-HCSL output.
• PCIe Compliance: Optimized for PCI Express clock distribution, supporting frequencies up to 167 MHz.
• Low Voltage Operation: Designed for 1.5 V systems with a supply voltage range of 1.425 V to 1.575 V.
• Spread Spectrum Support: Compatible with spread spectrum inputs to assist in electromagnetic interference reduction.

Applications

• PCI Express clock routing in server and workstation motherboards.
• System-on-Chip (SoC) clock distribution networks requiring low jitter.
• High-speed digital interfaces utilizing PCIe Gen1 through Gen3 standards.

Procurement Notes

This component is identified as obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of availability should focus on the recommended replacement part number 9DMV0131AKILF or existing stock from authorized distributors. Ensure that any sourced units are verified for authenticity and storage conditions prior to integration into designs.

Selection Notes

When selecting this component, confirm compatibility with the target system's 1.5 V power domain and HCSL/LP-HCSL signaling levels. Verify that the 167 MHz maximum frequency meets the specific PCIe generation requirements. Consider the 16-VFQFPN package dimensions for PCB layout constraints and ensure thermal management aligns with the -40°C to +85°C operating range.

Part Context

The 9DMV0131BKILFT belongs to the 9DMV01x1 family of PCIe clock multiplexers. It serves as a successor or alternative to earlier IDT/Integrated Device Technology parts in the same category. The 'B' suffix typically denotes specific manufacturing lot or revision details, while 'KILF' indicates the tape and reel packaging format with lead-free composition.

Replacement Considerations

Renesas recommends the 9DMV0131AKILF as a direct substitute. This replacement maintains similar functional characteristics but may differ in minor manufacturing revisions. Verify pinout compatibility and electrical parameters against the new datasheet before implementation.
