Abstract
A plurality of circuit blocks that output digital signals with different sampling frequencies are connected to data buses in common. One of outputs of the circuit blocks is selected and the output is sent to a sampling rate converter circuit block through the data buses. Each of the circuit blocks has a tri-state buffer at its output stage. With an output enable signal, a desired circuit block can be selected.
