9FGL0451AKILF 4-Output 3.3V PCIe Clock Generator
The 9FGL0451AKILF is a high-performance 4-output PCIe clock generator from Renesas Electronics, engineered specifically for PCI Express Gen1 through Gen5 applications. This device belongs to IDT's 3.3V Full-Featured PCIe clock generator family and delivers four independent 100 MHz differential clock outputs. With an ultra-low jitter of just 81 ps, the 9FGL0451AKILF ensures signal integrity and timing precision essential for high-speed data transmission systems, networking equipment, servers, and storage devices. The device operates from a 3.3V supply with a low current consumption of 30 mA, making it both power-efficient and straightforward to integrate into modern system designs.
The 9FGL0451AKILF is ideally suited for a wide spectrum of high-performance applications. Primary target markets include servers and high-performance computing platforms, data center accelerators, enterprise storage systems, networking switches and routers, as well as embedded systems and industrial control equipment. Its PCIe Gen1–5 compliance makes it a versatile solution for both legacy and next-generation interface designs. The device's integrated terminations and flexible spread spectrum options enable designers to achieve clean, reliable clock distribution while minimizing external component count—a critical advantage in space-constrained, high-density PCB layouts.
