RC19008A100GND#KB0

Overview

The RC19008A100GND#KB0 is an eight-output PCIe Gen7 clock buffer manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 3.6 V and supports input frequencies up to 400 MHz. The device features LP-HCSL outputs with selectable 100 Ω output impedance, eliminating the need for external termination resistors. Key electrical specifications include a maximum propagation delay of 1.8 ns and an additive phase jitter of 30 fs RMS. It functions in temperatures from -40°C to +105°C and is housed in a 5 mm × 5 mm 40-VFQFPN package.

Feature Summary

• PCIe Gen1–Gen7 compliance with backward compatibility
• LP-HCSL outputs supporting 100 Ω impedance
• Ultra-low additive jitter (30 fs typ) and 1.8 ns max propagation delay
• Flexible startup sequencing (FSS) and automatic clock parking (ACP)

Applications

• AMD Genoa power and timing systems
• PCIe Gen5/6 infrastructure designs
• DDR5 memory controller clock distribution

Procurement Notes

Verify the specific ordering suffix #KB0 against official Renesas documentation to confirm pinout and packaging details, as suffixes can indicate variations in reel type or moisture sensitivity levels. Ensure the component meets RoHS requirements for the target assembly process. Cross-reference the manufacturer part number with distributor catalogs to confirm current availability status and long-term supply commitments.

Selection Notes

Select this component when designing high-speed PCIe interfaces requiring low jitter and flexible output drive capabilities. The 100 Ω impedance version is suitable for applications needing integrated termination. Consider the 40-VFQFPN package dimensions for PCB layout constraints. Verify that the input signal source matches the supported LVDS or HCSL input types for optimal performance.

Part Context

This part belongs to the RC19008 family of PCIe Gen7 clock buffers. It shares core architectural features with other variants like the RC19008A100GND#BB0 but may differ in packaging or shipping configuration based on the suffix. The family is designed to support next-generation server and communication infrastructure requirements.

Replacement Considerations

The RC19008A100GND#BB0 is a related variant within the same product family. Verify if the #BB0 suffix offers identical electrical characteristics and pin compatibility before substitution. No other public substitute part numbers are confirmed.
