9FGL0441

4-Output 3.3V PCIe Clock Generator 9FGL0441 / 9FGL0451 Datasheet Description The 9FGL0441 / 9FGL0451 devices are 4-output clock generators in IDT's 3.3V Full-Featured PCIe family. Each output has a dedicated OE# pin for clock management. Two different spread spectrum levels in addition to spread off are supported. The 9FGL0441 / 9FGL0451 supports PCIe Gen1–4 Common Clocked architectures (CC) and PCIe Separate Reference no-Spread (SRnS) and Separate Reference Independent Spread (SRIS) clocking architectures. Typical Applications ▪ Servers/High-Performance Computing/Accelerators ▪ Storage ▪ Embedded Systems/Industrial Control Output Features ▪ Four 100MHz Low-Power HCSL (LP-HCSL) DIF pairs: 9FGL0441 default Zo = 100Ω 9FGL0451 default Zo = 85Ω ▪ One 3.3V LVCMOS REF output; Wake-On-LAN (WOL) support ▪ See AN-891 for easy AC-coupling to other logic families Key Specifications ▪ PCIe Gen1–4 CC compliant; Gen2–3 SRIS compliant ▪ DIF cycle-to-cycle jitter < ...
