    摘要: Methods and apparatus for synchronizing communications between a first and a second device include serially communicating a frame having a first format from a first device to a second device, wherein only a frame synchronization timeslot (F1) is asserted. The serially communicated frame having the first format is sampled by the second device until the asserted F1 timeslot is detected. The second device serially communicates a frame having a second format to the first device, wherein only a frame synchronization timeslot (R1) is asserted. The serially communicated frame having the second format is sampled by the first device until the asserted R1 timeslot is detected. The first device establishes synchronization when these steps are successfully repeated. On the second sampling to detect the F1 timeslot, however, the sampling is windowed to less than one timeslot within the expected occurrence of the F1 timeslot.
