The CDM-7 clock distribution and timing reference module is a PCIe card that provides 10MHz and 1PPS signals for up to seven devices that need precise synchronization.

The CDM-7 is ideal for PCIe-based Software-Defined Radios (SDR) installed in rack-mounted or desktop PCs, and can also be used for any other application that requires a precise timing reference.

Each card has an OCXO that can phase lock to a variety of external timing references, including multi-constellation GNSS.
