  • Transmission circuit of a line encoded signal on a telephone line
    Patent number: 5751775
    Abstract: A full duplex transmission circuit for a signal having alternating synchronization words with data words. The circuit comprising a phase-locked loop including a frequency synchronizer adapted to provide an emission clock signal. A sampling signal having its phase locked on the shift between an emitted signal and a received signal is generated using a clock signal provided by the phase-locked loop. The circuit includes circuitry for imparting to the frequency synchronizer a frequency multiplier function to reduce a duration of phase skips of the sampling signal.
