Abstract

An eye opener circuit is provided which performs a data re-timing/eye opening function on a data signal after having been corrupted by jitter. The circuit uses a PLL driven by a clock source which was the same clock source used in timing the data signal originally. The PLL generates a local clock used to re-time the data. A phase error may be introduced into the PLL, or into the data signal.
