9FGL6241AQ201LTGI

Overview

The 9FGL6241AQ201LTGI is a PCIe clock generator and buffer from Renesas Electronics, designed for high-speed serial link applications. It features two differential LP-HCSL outputs with integrated 100Ω terminations, eliminating the need for external resistors. The device supports Common Clock (CC) and Separate Reference Independent Spread (SRIS) architectures, accommodating PCIe Gen 1 through Gen 6 standards. Operating at 3.3V, it accepts 25MHz or 33.33MHz reference inputs via crystal or LVCMOS/HCSL signals. The component is housed in a compact 4mm x 4mm 28-VQFP-N package.

Feature Summary

• Integrated 100Ω differential output terminations reduce board space and component count
• Supports CC and SRIS clocking architectures with SMBus-selectable spread spectrum options
• Automatic input clock detection and mode switching for system reliability
• Compact 4mm x 4mm 28-VQFP-N package suitable for dense PCB layouts

Applications

• Single and dual-ported NVMe SSDs
• PCIe master/slave clock distribution systems
• Clock multiplexing applications requiring low jitter performance

Part Context

This part belongs to the 9FGL6241/6251 family of intelligent PCIe clock buffers and generators. While the 9FGL6251 variant typically includes an internal crystal option, the 9FGL6241 series focuses on external reference configurations. These devices are engineered to meet the stringent jitter requirements of modern PCIe interfaces, ensuring signal integrity across multiple generations of the standard.

Replacement Considerations

Direct pin-to-pin replacements within the same family include the 9FGL6241AP202NDGI. Designers should verify that the specific suffix indicates compatible termination impedance and package type before substitution.
