在工艺中，如EP 0813321 A2，尤其是可以看到的，该时钟频率由来自脉冲持续时间相应高频振荡器时钟的装置的。 振荡器时钟另一方面作为其生成在到达系统和数据传输周期的阈值的计数器的时钟。 然而，在以往的位序列未知的数字数据脉冲的脉冲电平permante一个同步后是不可能的，重复再同步必须在这些通过公知的数字数据脉冲的通过重新同步脉冲来实现。 由同步脉冲和数据脉冲是曼彻斯特编码和在脉冲边沿变化集中发生被用作同步定时，发生的振荡周期时表示期间每两个连续的同步时间点之间的周期中的计数值计数的时间域的时钟频率，以及数据传送时钟发生器至少根据同步脉冲是 在同步时间接管的计数值和从该数据传送时钟发生器的相应的当前有效的时钟频率可frequenzsynchronisert。 数据脉冲和同步时间点之间的从而发生时间偏移是由数据脉冲的逻辑电平的一个时间交错的扫描考虑。 特别用作在用于机动车辆的乘员保护装置的总线系统的数据传输的方法

In processes, such as EP 0813321 A2, in particular, apparent from the clock frequency is derived by means of a correspondingly high frequency oscillator clock from the pulse duration. The oscillator clocks serve the other hand, as the clock for the counters that generate when reaching threshold system and data transfer cycles. Since, however, a permanent post-synchronization is not possible with a conventional bit string of digital data pulses unknown impulse level, a repeated re-synchronization must be realized in these according to a known number of data pulses by re-sync pulses. By the synchronization and data pulses are Manchester encoded, and a center of the pulse occurring edge change is used as a synchronization timing, the oscillator cycles occurring are used as the clock frequency representing the time domain counted during the time period between each two successive synchronization points in a count and the data transfer clock generator at least according to a synchronization pulse at the synchronization time accepts the count and from this the actual valid clock, the data transfer clock generator can be frequenzsynchronisert. The occurring time shift between the data pulses and the synchronization points is taken into account by a time-staggered scanning of the logic level of the data pulses.
