    • A MicroTCA system is disclosed that 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.
    • 公开了一种包括MCH,与MCH连接的时钟卡和多个AMC的MicroTCA系统。 时钟卡包括时钟选择单元,用于选择和输出时钟源和相位锁定单元,用于根据由时钟卡的时钟选择单元选择的时钟源产生系统同步时钟。 MCH包括时钟驱动单元,被配置为将由时钟卡产生的系统同步时钟驱动到与MCH连接的多个AMC。 还提供了时钟卡,级联的MicroTCA载体和用于提供时钟的方法。 以这种方式,简化了MicroTCA时钟系统的实现,降低了多个级联MicroTCA载波的整体配置成本。
