The CDCM9102 is a low-jitter clock generator designed to provide reference clocks for communications standards such as PCI Express™. The device supports up to PCIE gen3 and is easy to configure and use. The CDCM9102 provides two 100-MHz differential clock ports. The output types supported for these ports include LVPECL, LVDS, or a pair of LVCMOS buffers. HCSL signaling is supported using an AC-coupled network. The user configures the output buffer type desired by strapping device pins. Additionally, a single-ended 25-MHz clock output port is provided. Uses for this port include general-purpose clocking, clocking Ethernet PHYs, or providing a reference clock for additional clock generators. All clocks generated are derived from a single external 25-MHz crystal.
