  • Serial data clock recovery circuit using dual oscillator circuit
    Patent number: 5418496
    Abstract: A serial data clock receiver circuit (11) is provided that synchronizes a clock signal to data. The serial data clock receiver circuit (11) comprises a control circuit (21), a dual oscillator circuit (19), and a phase locked loop circuit (22). The control circuit (21) arms the dual oscillator circuit (19) for being enabled during an idle period. The phase locked loop circuit (22) provides a reference voltage for the dual oscillator circuit (19). The dual oscillator circuit (19) is responsive to both the data and control circuit (19) for providing a clock signal.
