I would like to use the Sigma DSP AD1941 to equalize music. But I have to know which clock frequency has got the I²S port (serial data I/O port) because I want to transmit the music via FM-Transmitter to a car-radio. The FM-Transmitter input must have a minimum clock frequency of 2 MHz.
I have looked through the datasheet but I cannot find the clock frequency of the I²S output. So I hope you can help me.
