9DMV0131BKILF

Overview

The 9DMV0131BKILF is a clock multiplexer manufactured by Renesas Electronics Corporation, designed for PCI Express (PCIe) applications. It functions as a 2:1 multiplexer with a maximum operating frequency of 167 MHz. The device operates on a supply voltage ranging from 1.425 V to 1.575 V and features LVDS differential inputs paired with LP-HCSL differential outputs. Packaged in a 16-VFQFPN (3x3 mm) surface-mount housing with an exposed pad, it supports a commercial temperature range of -40°C to +85°C. This component is part of the PCIe clock distribution family, providing signal routing capabilities for high-speed serial interfaces.

Feature Summary

• 2:1 Multiplexing Ratio: Selects between two differential input sources to drive a single differential output channel.
• PCIe Compliance: Optimized for PCI Express clock distribution architectures, supporting frequencies up to 167 MHz.
• Signal Standards: Accepts LVDS differential inputs and provides LP-HCSL differential outputs for low-power signaling.
• Compact Packaging: Utilizes a space-saving 16-VFQFPN package measuring 3x3 mm with a 0.5 mm pitch.

Applications

• PCI Express clock routing in server and workstation motherboards.
• Clock distribution networks for PCIe expansion cards and add-in boards.
• High-speed data acquisition systems requiring precise clock source selection.
• Telecommunications infrastructure utilizing PCIe-based interconnects.

Procurement Notes

Verify the current manufacturing status before procurement, as this specific part number may be obsolete or superseded by newer revisions within the same product family. Confirm that the 1.5V supply voltage and LVDS-to-LP-HCSL signal conversion align with the target system design requirements. Ensure compatibility with the 16-VFQFPN footprint during PCB layout finalization.

Selection Notes

Select this component when a 2:1 mux with LVDS inputs and LP-HCSL outputs is required for PCIe Gen1-Gen3 applications. Compare against the 9DMU0131AKILF for potential pin-compatible alternatives if available. Evaluate power consumption constraints, as the 1.5V operation targets ultra-low-power designs. Verify thermal performance within the -40°C to +85°C range for the intended environment.

Part Context

The 9DMV0131BKILF belongs to Renesas' portfolio of PCIe clock multiplexers, which also includes variants like the 9DMU0131AKILF and 9DMV0441BKILF. These devices address the need for flexible clock source management in complex digital systems. The 'V' series typically denotes specific voltage or feature sets within the broader 9DM family, distinguishing them from other generations or power domains.

Replacement Considerations

The 9DMU0131AKILF is listed as a manufacturer-recommended alternative. Verify electrical parameter equivalence, specifically the 1.5V supply and LVDS/LP-HCSL interface compatibility, before substituting. Check for any differences in switching modes or termination resistors that might impact board-level performance.
