<p>The present invention discloses a MicroTCA system, which includes: an MCH, a clock card connected with the MCH, and multiple AMCs. The clock card includes: a clock selecting unit, configured to select and output a clock source; and a phase-lock unit, configured to generate a system synchronization clock according to the clock source selected by the clock selecting unit of the clock card. The MCH includes: a clock drive unit, configured to drive the system synchronization clock generated by the clock card to multiple AMCs connected with the MCH. A clock card, a cascaded MicroTCA carrier, and a method for providing a clock are also provided. In this way, the implementation of the MicroTCA clock system is simplified, and the whole configuration cost of multiple cascaded MicroTCA carriers is reduced.</p> |
