Clock Generator 32-Pin VQFN EP T/R

The CDCM9102 is a low-jitter clock generator designed to provide reference clocks for communications standards such as PCI Express.The device 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.
