Abstract
A synchronization pattern detector is disclosed. The synchronization pattern detector includes a plurality of cost function engines which each calculate a partial cost of a subset of the incoming data bits. The cost function engines are arranged in a two dimensional array where each row processes data samples associated with a particular phase of the incoming data bits. These partial costs are summed together to calculate a total cost for a particular symbol stream. Summing circuits are configured to calculate costs for various scenarios, such as transmit baudrate equal to the receiver baudrate; transmit baudrate slower than the receiver baudrate; and transmit baudrate faster than the receiver baudrate. In addition to detecting the synchronization pattern, the detector may also provide information that is used to adjust parameters of the read circuit to better align the receiver baudrate to the transmit baudrate.
