    • A data processing apparatus receives a message containing a sync break interval with a unique bit pattern and a sync field interval identified by the sync break interval. A timing property of the sync field interval specifies the length of bit periods of the message. A clock source circuit supplies a sampling clock signal to define time points for sampling bits from the message. The clock source circuit adapts a frequency of the sampling clock signal to the timing property of the sync field interval. The clock source circuit searches for potential sync break intervals that match the unique bit pattern for a range of bit period values and verifies for each potential sync break interval whether the sync field interval identified by that potential sync break interval specifies a bit period with a duration so that the sync break interval matches the unique pattern for the specified bit period, as a condition prior to supplying the sampling clock signal at the adapted frequency specified by the sync field interval identified by the potential sync break interval. Supply of sampling clock signals is preferably suppressed after an end of a preceding message until said condition is met.
    • 数据处理装置接收包含具有由同步中断间隔识别的唯一位模式和同步字段间隔的同步中断间隔的消息。 同步字段间隔的定时属性指定消息的位周期的长度。 时钟源电路提供采样时钟信号以定义来自消息的采样位的时间点。 时钟源电路使采样时钟信号的频率适应于同步信号间隔的定时特性。 时钟源电路搜索与位周期值范围的唯一位模式匹配的潜在同步中断间隔,并验证每个潜在同步中断间隔,无论由该潜在同步中断间隔识别的同步字段间隔是否指定持续时间的位周期 使得同步中断间隔与指定位周期的唯一模式匹配,作为在由潜在同步中断间隔识别的同步字段间隔指定的适配频率提供采样时钟信号之前的状态。 优选地,在先前消息结束之后抑制采样时钟信号的提供直到满足所述条件。
