    • A quantized channel rate and corresponding rate multiplier is determined on a transmitter-side of a communication system based on a measured minimum required bandwidth. In certain embodiments, the quantized data rate may be an integer multiple of the system's reference clock. The determined rate multiplier is then transmitted to the receiver-side at a default data rate prior to or near the beginning of a data transmission session, such as upon initialization. Prior to transmission, the data stream may be padded with some determined amount of null data such that the actual transmitted data rate is approximately equal to the quantized channel rate, and the receiver-side can readily recover the data clock using its known reference clock and the previously-provided rate multiplier.
    • 基于所测量的最小所需带宽,在通信系统的发射机侧确定量化信道速率和相应的速率乘数。 在某些实施例中,量化数据速率可以是系统参考时钟的整数倍。 然后,确定的速率乘数在诸如初始化之前的数据传输会话开始之前或之后以默认数据速率发送到接收机侧。 在传输之前,可以用某些确定量的空数据填充数据流,使得实际发送的数据速率近似等于量化的信道速率,并且接收机侧可以使用其已知的参考时钟容易地恢复数据时钟, 以前提供的速率倍数。
