ACOUSTIC APPARATUS WITH SHARED CLOCK

摘要

An acoustic apparatus includes a first digital microphone having a first clock pin, a second digital microphone having a second clock pin, an application processor having a third clock pin, a first interface that couples the first digital microphone and the application processor, and a second interface that couples the first digital microphone, the second digital microphone, and the application processor. The acoustic apparatus further includes a clock that connects to the first clock pin, the second clock pin, and the third clock pin, wherein first data is transmitted on a first clock edge, and wherein second, different data is transmitted on a second other clock edge.
