System and method for high-speed skew-insensitive multi-channel data transmission

Abstract From the Canadian patent

A method and apparatus is disclosed that receives a multi-channel digital serial encoded signal and converting it into a synchronized set of binary characters. A charge pump phase-locked loop receives a transmitted reference clock and derives a multi-phase clock from the reference clock. The multiphase clock is used to control a plurality of multi-bit block assembly circuits. Each assembly circuit receives one channel of the digital signal and produces a multi-bit block or character. The multi-bit block assembly circuit includes an oversampler, a digital phase-locked loop and a byte synchronizer. The oversampler ovesamples the received digital signal under control of the multiphase …
