  • Apparatus and method of preventing cell data loss during clock switching
    Patent number: 5903543
    Abstract: In a clock system having active and standby clocks for synchronizing cell data flow in a data system, and for preventing cell data loss during active to standby clock switching, a prevent circuit maintains the active clock cycle signal during the active/standby clock switching to ensure the proper setup time before the active clock is disabled. The prior standby clock will become active during the maintenance period, thereby providing the proper setup time before and after switching, permitting system redundancy without loss of data.
