Abstract:
1. A method of communicating payload data from a first device to a second device over a plurality of low voltage differential signaling (LVDS) channels, the method comprising: transmitting payload data and synchronization information from the first device to the second device over N LVDS channels; wherein N is an integer, transmitting a word clock from the first device to the second device, where the word clock is synchronized to the payload data; receiving the payload data and synchronization information of each of the N LVDS channels at a corresponding one of N LVDS receivers of the second device; receiving the word clock at the second device; generating M LVDS receive clocks from the word clock, each of the M LVDS receive clocks having a same frequency that is P times a frequency of the word clock, wherein P an integer, and each of the M LVDS receive clocks having a different phase with respect to each other; wherein M is an integer, and at each of the N LVDS receivers: correlating the synchronization information with a reference word using each of the M LVDS receive clocks to produce a correlation value for each of the M LVDS receive clocks, selecting a selected LVDS receive clock producing a greatest correlation value, and receiving the payload data for the corresponding LVDS channel ( 160 ) using the selected LVDS receive clock.
