A channel data extracting circuit for extracting data for each channel from a frame in which byte data of channels are multiplexed includes a Banyan unit and data control unit. The Banyan unit distributes data for respective channels by Banyan switches of planes corresponding to the channels, and sequentially aligns word data. The data control unit transmits to the Banyan unit a control signal representing a channel to which data belongs, and controls the operations of the Banyan switches. A channel data extracting method is also disclosed.
