9DBL0253 Overview
The 9DBL0243 / 9DBL0253 devices are 3.3V members of IDT's Full-Featured PCIe clock family. They support PCIe Gen1 4 mon Clock (CC) architectures and also support NVLINK applications. The 9DBL0243 / 9DBL0253 parts have a Loss of Signal (LOS) indicator to support fault-tolerant, high-reliability systems.
