The 9FGL0841/51 devices are 8-output 3.3V PCIe Gen1–5 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 9FGL0841/51 supports PCIe Gen1–5 Common Clocked architectures (CC), PCIe Separate Reference no-Spread (SRNS) and Separate Reference Independent Spread (SRIS) clocking architectures.
For information regarding evaluation boards and material, please contact your local sales representative.
