9DBV0241AKILFT

Overview

The 9DBV0241AKILFT is a 2-output, 1.8V PCIe Very-Low-Power (VLP) clock buffer manufactured by Renesas Electronics. It supports differential LP-HCSL output signaling with an operating frequency range of 30 MHz to 137.5 MHz. The device features integrated 100Ω terminations for direct connection to transmission lines and accepts HCSL-compatible differential inputs. It includes spread spectrum compatibility for EMI reduction and offers SMBus-selectable features for configuration optimization.

Feature Summary

• Two differential outputs providing LP-HCSL signaling with integrated 100Ω termination resistors
• Supports PCIe Gen1-3 architectures with input frequencies from 30 MHz to 137.5 MHz
• SMBus interface allows selectable slew rates, output amplitudes, and PLL bandwidth settings
• Low power consumption of approximately 35mW in PLL mode

Applications

• PCI Express Gen1/Gen2/Gen3 zero-delay fanout buffers
• Clock distribution systems requiring low electromagnetic interference
• High-speed digital interfaces needing precise timing synchronization

Part Context

This component belongs to the IDT/Renesas 9DBV0241 family of 1.8V VLP PCIe clock buffers. It is designed to replace legacy buffering solutions by reducing board space and power requirements while maintaining signal integrity through integrated impedance matching.

Replacement Considerations

Verify that the replacement part supports the specific PCIe generation required by the design. Ensure the new component accommodates the same voltage levels and pinout configurations if a direct footprint swap is intended.
