    • An apparatus and method for cross clock domain interference cancellation is provided to a communication system which includes a transmitter operated in a first clock domain and a receiver operated in a second clock domain. The apparatus comprises a First-In-First-Out (FIFO) circuit and a cancellation signal generator. The FIFO circuit receives a digital transmission signal of the transmitter in the first clock domain, and outputs the digital transmission signal in the second clock domain according to an accumulated timing difference between the first and second clock domains. The cancellation signal generator generates a cancellation signal for canceling an interference signal received by the receiver according to the digital transmission signal outputted by the FIFO circuit. The interference signal is generated in response to the digital transmission signal. The cancellation signal generator adjusts the cancellation signal according to a phase difference between the interference signal and the cancellation signal.
    • 一种用于交叉时钟域干扰消除的装置和方法被提供给包括在第一时钟域中操作的发射机和在第二时钟域中操作的接收机的通信系统。 该装置包括先进先出(FIFO)电路和消除信号发生器。 FIFO电路在第一时钟域中接收发射机的数字传输信号,并根据第一和第二时钟域之间的累积时序差输出第二时钟域中的数字传输信号。 消除信号发生器根据由FIFO电路输出的数字传输信号产生消除由接收机接收的干扰信号的消除信号。 响应于数字传输信号产生干扰信号。 消除信号发生器根据干扰信号和消除信号之间的相位差来调整抵消信号。
