Description
The 9QXL1200 is an ultra-high performance PCIe Gen7 fanout buffer that is backward compatible with earlier PCIe generations. It features a loss-of-signal (LOS) output for system monitoring and resiliency. The device also incorporates power-down tolerant (PDT) and flexible startup sequencing (FSS) capabilities, simplifying system design.
