Electronic device and operation method therefor

A method of operating an electronic device, the method comprising:

• based on a communication state change event of the electronic device occurring, setting a spread spectrum method of a spread spectrum clock generator (SSCG) of the electronic device to a first spread spectrum method and setting a spread ratio of the SSCG to a first spread ratio;
• determining whether the electronic device is communicatively coupled to at least one of a first wireless communication and a second wireless communication;
• based on the electronic device being communicatively coupled to the at least one of the first wireless communication and the second wireless communication, identifying a frequency band of a channel of the at least one of the first wireless communication and the second wireless communication communicatively coupled to the electronic device;
• determining whether at least one of a first frequency of a first operating frequency range and first multiplication frequencies of the first frequency is in the frequency band of the channel;
• and
• based on the first frequency and the first multiplication frequencies of the first frequency being outside of the frequency band, maintaining the first spread spectrum method and the first spread ratio so that the SSCG generates a first spread spectrum clock signal based on the first spread spectrum method and the first spread ratio,
• wherein the first operating frequency range is determined based on a center frequency of the first spread spectrum clock signal, the first spread spectrum method, and the first spread ratio.

A non-transitory computer-readable storage medium storing computer-executable instructions for performing data communication that, when executed by at least one processor of an electronic device, cause the electronic device to:

• based on a communication state change event of the electronic device occurring, set a spread spectrum method of a spread spectrum clock generator (SSCG) of the electronic device to a first spread spectrum method and set a spread ratio of the SSCG to a first spread ratio;
• determine whether the electronic device is communicatively coupled to at least one of a first wireless communication and a second wireless communication;
• based on the electronic device being communicatively coupled to the at least one of the first wireless communication and the second wireless communication, identify a frequency band of a channel of the at least one of the first wireless communication and the second wireless communication communicatively coupled to the electronic device;
• determine whether at least one of a first frequency of a first operating frequency range and first multiplication frequencies of the first frequency is in the frequency band of the channel;
• and
• based on the first frequency and the first multiplication frequencies of the first frequency being outside of the frequency band, maintain the first spread spectrum method and the first spread ratio so that the SSCG generates a first spread spectrum clock signal based on the first spread spectrum method and the first spread ratio,
• wherein the first operating frequency range is determined based on a center frequency of the first spread spectrum clock signal, the first spread spectrum method, and the first spread ratio.
