Methods and apparatus for synchronizing data transferred across a multi-pin asynchronous serial interface
Abstract:
Methods, devices and systems are provided for word synchronizing multiple serial data bitstreams (106) with a serial framing signal (106A). Offset values (420) are determined (512) from the relative locations of predetermined data correlation values (107) stored within the data buffers during a correlation mode to indicate the amount of skew observed between the framing channel and each of serial data channels. Data received during subsequent operation of each data stream is stored a buffer (402), and the framing signal (106A) is monitored to identify a boundary between data words. When a frame boundary occurs, parallel data is extracted from the buffer using the previously-stored offset values to compensate for bit skew between the data and framing channels.
