ABSTRACT:
The audio system having a master clock, a serial port clocked according to a serial clock from the audio system, a programmable audio functional circuitry programmable and operable at a plurality of sample rates, and a rate selection control logic which sense a ratio between the serial clock and the master clock. The serial clock is derived from the master clock. The rate selection control logic reprograms the audio functional circuitry based on the ratio, to operate at one of the plurality of sample rates in response to a change in the clock rate of the serial clock, such that the audio functional circuitry operates at another of the plurality of sample rates.
