9FGL0251

2-Output 3.3V PCIe Clock Generator 9FGL0241 / 9FGL0251 Datasheet Description The 9FGL0241 / 9FGL0251 devices are 2-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 9FGL0241 / 9FGL0251 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 ▪ Two 100MHz Low-Power HCSL (LP-HCSL) DIF output pairs: 9FGL0241 default Zout = 100Ω 9FGL0251 default Zout = 85Ω ▪ One 3.3V LVCMOS REF output with 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-c...
