9DB401BGLFT

Application Specific Clock/Timing Overview

The Renesas Electronics 9DB401BGLFT is a zero-delay buffer clock driver designed for PCI Express applications. It features one HCSL differential input and four true LVDS outputs, providing a 1:4 fan-out ratio. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports maximum frequencies up to 400 MHz. Packaged in a 28-TSSOP housing, it functions reliably between 0°C and +70°C with a typical operating current of 115 mA.

Application Specific Clock/Timing Feature Summary

• Zero-delay buffering architecture for low-jitter signal distribution
• Single HCSL differential input driving four LVDS outputs
• Supports PCIe Gen1 and Gen2 data rates up to 400 MHz
• Operates on a single 3.3V nominal power supply (3.135V–3.465V)

Application Specific Clock/Timing Applications

• PCI Express clock distribution networks
• High-speed digital system timing synchronization
• Server and storage controller board designs

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest documentation to confirm pinout compatibility and electrical specifications. Cross-reference the part number with official Renesas databases to ensure the component matches the required RoHS compliance status and package dimensions before finalizing procurement orders.

Application Specific Clock/Timing Selection Notes

Select this component when a single-ended or HCSL source must drive multiple LVDS loads with minimal skew. Ensure the design requires a 1:4 split ratio and operates within the 3.3V domain. Verify that the thermal requirements of the TSSOP-28 package align with the system's cooling capabilities for continuous operation at maximum frequency.

Application Specific Clock/Timing Part Context

This device belongs to the 9DB series of clock buffers from Renesas, formerly IDT. It serves as a critical timing element in high-speed serial interfaces, replacing older discrete logic solutions to reduce board space and improve signal integrity in complex electronic systems requiring precise clock alignment.

Application Specific Clock/Timing Replacement Considerations

The ICS9DB401BGLFT is an alias for this component. Check for newer revisions in the 9DB401 family if long-term availability is a concern, ensuring any substitute maintains the same 1:4 LVDS output configuration and HCSL input compatibility.
