DESCRIPTION

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.
