Abstract
A method and system communicates payload data over a plurality of low voltage differential signaling (LVDS) channels (50). First device (100) transmits the payload data and synchronization information to the second device (150) over N LVDS channels (50), along with a word clock synchronized to the payload data. The second device generates M LVDS receive clocks from the word clock, each having a same frequency that is P times a frequency of the word clock, and each having a different phase. Each of N LVDS receivers (160) of the second device (150): correlates the synchronization data 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; selects a selected LVDS receive clock producing a greatest correlation value; and receives the payload data for the corresponding LVDS channel (50) using the selected LVDS receive clock.
