I²S Interface (In / Out)

I²S Outputs in TQFP 100 Package

Two digital stereo outputs (I²S compatible) are available for routing the demodulated signal or a

converted input audio signal to an external device or perform an external delay. In this case, the

I2SO_DATA0 and I2SO_DATA1 signals are available with all I²S inputs active. The STV82x8 drives

the serial bus (I2SO_SCLK,I2SO_LR_CLK, I2SO_DATA0, and I2SO_DATA1) in master mode in

64.fs format with a sampling frequency (fs) of 48 kHz. The I2S_PCM_CLK signal can be used as a

master clock if required for the slave interface. Both standard and non-standard modes are

available. .
