描述
The 9FGL0241/51 devices are 2-output 3.3V PCIe Gen 1–6 clock generators. Each output has a dedicated OE# pin supporting PCIe CLKREQ# functionality. Two different spread spectrum levels, in addition to spread off, are supported. The 9FGL0241/51 supports PCIe Gen 1–6 Common Clocked architectures (CC), PCIe Separate Reference no Spread (SRNS), and Separate Reference Independent Spread (SRIS) clocking architectures.
