  • Publication number: 20200145182
    Abstract: One embodiment relates to a transmitting device, a receiving device, and the like for preventing increases in the number of communication links, power consumption, and circuit layout area. The transmitting device includes a high-speed signal generator, a low-speed signal generator, and a signal superimposing unit. The high-speed signal generator generates a high-speed signal having a limited frequency band. The low-speed signal generator generates a low-speed signal having a frequency lower than the frequency band of the high-speed signal. The signal superimposing unit outputs a superimposed signal of the high-speed signal and the low-speed signal. The receiving device includes a signal separator and a recovery unit. The signal separator separates the received signal into the high-speed signal and the low-speed signal. The recovery unit performs frequency tracking based on the separated low-speed signal and performs phase tracking based on the separated high-speed signal.
