9DB1933AKLFT

Overview

The Renesas 9DB1933AKLFT is a zero-delay buffer designed for high-speed differential signaling. It supports PCIe Gen3 requirements while maintaining backward compatibility with Gen2 and Gen1 standards. The device features an 8-output configuration to distribute clock signals across multiple endpoints. It operates within a supply voltage range of 1.7 V to 1.9 V and supports input frequencies up to 200 MHz. The component is housed in a 48-lead VFQFPN package and functions reliably within an operating temperature range of 0°C to +70°C.

Feature Summary

• Supports PCIe Gen3 transmission requirements with backward compatibility for Gen2 and Gen1
• Provides eight output channels for clock distribution
• Operates as a zero-delay buffer for signal integrity

Applications

• PCI Express Gen3 system designs
• High-speed data transmission interfaces
• Clock distribution networks requiring low jitter

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the procurement channel provides valid RoHS compliance certificates and moisture sensitivity level (MSL) ratings. Ensure the supplier source is authorized to guarantee component authenticity and traceability throughout the supply chain.

Selection Notes

Select this component when designing systems requiring PCIe Gen3 compliance with legacy support. The 8-output architecture suits applications needing extensive fan-out from a single source. Verify that the 1.7 V to 1.9 V supply voltage aligns with the target board's power rails. Consider the 48-lead VFQFPN package dimensions for PCB layout constraints and thermal management requirements.
