At least one embodiment of the present disclosure provides a frequency divider, an electronic device and a frequency dividing method. The frequency divider includes a duty cycle correction circuit and a frequency divider circuit. The duty cycle correction circuit is configured to receive a first clock signal, and perform a first processing on the first clock signal to generate a first processed signal. The frequency dividing circuit is configured to receive the first processed signal, and perform a second processing on the first processed signal to generate a second processed signal. The duty cycle correction circuit is further configured to receive the second processed signal, and perform a third processing on the second processed signal to generate a third processed signal. The frequency divider can correct the duty cycle of the output clock signal while dividing the frequency.

Frequency divider, electronic device and frequency dividing method

A method, a detection circuit and an electronic device for detecting timing sequence of serializer are provided. The method for detecting a timing sequence of a serializer includes: sampling serial data to obtain first sampled serial data and second sampled serial data, wherein the serial data is obtained by parallel-serial conversion of parallel data used for detection by the serializer, and the first sampled serial data and the second sampled serial data respectively include values corresponding to different data bits of the serial data; performing logical operation between on the first sampled serial data and the second sampled serial data to obtain a first result signal; and performing timing sequence detection on the first result signal, wherein the timing sequence detection is used for detecting whether the timing sequence correctness of the serializer is correct.
