  • System and method for clock signal synchronization
    Patent number: 7864906
    Abstract: A system (101) for clock signal synchronization includes a data analyzer (104) and a synchronized clock signal generator (105) coupled to an RC oscillator (103). The data analyzer (104) generates a digital control signal representing the number of cycles of a reference signal of the RC oscillator (103) during an eight-bit period of an incoming token packet. The synchronized signal clock generator (105) uses the digital control signal to lock a clock signal to packets that have the same bit rate as the token packet.
