  • Circuit for eliminating metastable events associated with a data signal asynchronous to a clock signal
    Patent number: 5036221
    Abstract: A circuit for reducing the metastable events produced by a data signal asynchronous to a system clock signal is provided. The circuit includes an edge detector (32) for detecting a transistion of the data signal. The edge detector (32) controls a clock disable/reenable circuit (46) which will disable a system clock directed to a clocked device (36). The period of disablement is the minimum setup time for the clocked device (36). After the minimum setup time has passed, the disable/reenable circuit (42) will reenable the system clock to the clocked device (36). The system clock may be modified by a duration limit circuit (68). Data directed to the clocked device (36) may be delayed via a delay circuit (70).
