A phase adjustment device for dynamically synchronizing transmitters and receivers in memory bus systems, uses adjustment of data signal phase to compensate for phase-offset variations between devices in normal operation

摘要

The phase adjustment device includes transmit and receive phase adjusters configured to receive respective phase vector clock signals. Transmit and receive phase adjusters comprise respective clock phase interpolators that generate transmit or receive clocks with phase determined in accordance with the appropriate digitally stored transmit or receive phase value. INDEPENDENT CLAIMs are also included for the following: (a) A method for adjusting phase of data signals; (b) A system for data signal phase adjustment; (c) A data signal phase adjustment device.
