Clock and data recovery wherein an FB-DIMM is connected to signal path and null and sync frames control the FB-DIMM

摘要

Improved clock and data recovery involves transmitting one or more null frames prior to transmitting a sync frame. A receiving component detects for the sync frame to lock to a data signal sent on a signal path by a transmitting component. The one or more null frames transmitted prior to the sync frame results in a settling of the signal path prior to reception of the sync frame, thereby lessening or removing the effects of previously sent data on the sync frame.
