<p>PROBLEM TO BE SOLVED: To provide a packet transfer device that can simply send/receive even a packet including sampling data with a sampling frequency that is twice of a usual frequency. SOLUTION: Audio data D0-D2 are respectively received from input terminals DAI0-DAI2 synchronously with a half period of a sampling clock WCK. A transmission FIFO 8a receives data D0(n)-D2(n) with a sampling period (n) at a trailing of the sampling clock WCK 1 and receives data D0(n+1)-D2(n+1) with a sampling period (n+1) at a leading of the sampling clock WCK 1. A packet assembly section 9 assembles a packet comprising a header and data blocks DA0-DA5 and outputs the packet to a link layer controller 20.</p> |
