DATA TRANSMITTING AND RECEIVING SYSTEM INCLUDING CLOCK AND DATA RECOVERY DEVICE AND OPERATING METHOD OF THE DATA TRANSMITTING AND RECEIVING SYSTEM

A data transmitting and receiving system includes a first device including an encoder configured to encode row data to generate precoding data and a transmitter configured to transmit the precoding data through a transmission channel and a second device including an integrator configured to perform an integral on the precoding data, an integral sampler including a plurality of samplers configured to output sampling data based on an offset value and an output value of the integrator, a decoder configured to decode outputs of some of the samplers to generate decoded data, and a phase detector configured to detect a phase difference between the precoding data and a clock based on the decoded data and an output of another one of the samplers. 一种数据发送和接收系统，包括：第一设备，包括被配置为对行数据进行编码以生成预编码数据的编码器、以及被配置为通过传输信道发送预编码数据的发送器；以及第二设备，包括：积分器，被配置为对预编码数据执行积分；包括多个采样器的积分采样器，被配置为基于偏移值和积分器的输出值来输出采样数据；解码器，被配置为对一些采样器的输出进行解码以生成解码的数据；以及相位检测器，被配置为基于解码的数据和所述采样器中的另一个采样器的输出来检测预编码数据和时钟之间的相位差。
