Abstract
A digital microphone interface includes a phase generator for generating a phase signal. A clock generator produces a digital microphone clock at a selected frequency based on the frequency select signal, and supplying the digital microphone clock to a digital microphone. A first data latch, operably coupled to the phase generator, produces a stream of first data from a first channel of the digital microphone, based on a phase select signal and the phase signal.
