PURPOSE: To provide the phase difference absorption circuit absorbing a phase difference of data of an optional number of channels with simple circuitry. CONSTITUTION: The circuit is provided with a 1st n-ary (n) is an integer being 2 or over) counter 1a receiving a 1st frame signal as a load signal to count number of clocks, a 2nd n-ary counter 1b receiving a 2nd frame signal as a load signal to count number of clocks, a 1st latch circuit 2a latching the count of the 1st n-ary counter 1a based on the 2nd frame pulse signal, a 2nd latch circuit 2b latching the count of the 2nd n-ary counter 1b based on the 1st frame pulse signal, and a 1st shift register 3a expanding the 1st data into n-phases, a 2nd shift register 3b expanding the 2nd data into n-phases, a 1st selector 4a selecting one phase of an output of the 1st shift register 3a based on an output of the 1st latch circuit 2a and a 2nd selector 4b selecting one phase of an output of the 2nd shift register 3b based on an output of the 2nd latch circuit 2b. |
