The Word Clock Module (WCM) provides a galvanically isolated word clock input and two word clock outputs (BNC connectors). Both outputs have their own driver stages, providing an extremely low jitter signal. A push switch activates 75 Ohms termination for the hi-impedance input. SteadyClock, part of the PCI card, guarantees an excellent performance in all clock modes. Its highly efficient jitter suppression refreshes and cleans up any clock signal, and provides it as reference clock at the two outputs.

Installation is done in a convenient manner using the supplied bracket. No PCI slot on the motherboard is required. The module is internally connected via a 10-pin connector and a flat ribbon cable to the PCI card. Thanks to several LEDs (power, termination, LOCK) and the highly integrated concept of installation, first operation and usage are simple even for the inexperienced user.
