Abstract
Methods and apparatus are presented for obtaining clock data from Manchester coded serial data streams, in which received data is sampled at a sample rate higher than the serial data baud rate, multi-bit groups of transition bits are generated which individually indicate data transition locations in a corresponding multi-bit sampled data bit group, and clock data is derived using the multi-bit groups of transition bits without requiring receipt of synchronization data or receipt of a separate clock.
