9.2 Typical Application

Figure 9-1 shows a CDCDB400 typical application. In this application, a clock generator provides a 100-MHz reference to the CDCDB400 which then distributes that clock to PCIe endpoints. The clock generator may be a discrete clock generator like the CDCI6214 or it may be integrated in a larger component such as a Platform Controller Hub (PCH) or application processor.
