METHOD FOR COMBINING SIGNALS ON A DIGITAL INTERFACE
专利汇可以提供METHOD FOR COMBINING SIGNALS ON A DIGITAL INTERFACE专利检索，专利查询，专利分析的服务。并且A method for combining signals being conveyed across a digital interface (16) is disclosed. In one embodiment, a subharmonic ( f2) of a frequency (f0) is superimposed on asynchronous data. The subharmonic can be used to carry a frequency reference across the digital interface. In another embodiment, a time stamp algorithm is used to carry a time reference from a master circuit (50) to a slave circuit (52) across a digital interface. The transmission delay between the master circuit and slave circuit is measured. The master circuit transmits time correction messages to the slave circuit, based on the time the correction message is transmitted plus the transmission delay. In another embodiment, a reset signal is carried across a digital interface by discontinuing the transfer of a frequency reference for a predetermined time. A lowpass filter (54) can be used at the receiving side of the interface to recognize the absence of the frequency reference and initiate a reset procedure at that side.，下面是METHOD FOR COMBINING SIGNALS ON A DIGITAL INTERFACE专利的具体信息内容。
