STV82x7
I2S Interface (In / Out)
Both standard and non-standard modes are available, see
Figure 26
.
6.2
I2S Output
A digital stereo output (I2S compatible) is also available for routing the demodulated signal or a
converted input audio signal to an external device. In this case the I2S_DATA0 signal and all clock
signals are set as outputs by setting bit D6 in register RESET to 1. The STV82x7 I2S drives the
serial bus (SCLK, LR_CLK, I2S_DATA0) in master mode in 64.fs format with a sampling frequency
(f
s
) of 32 kHz. The I2S_PCM_CLK signal can be used as a master clock in 512.fs format if required
for the slave interface. Both standard and non-standard modes are available, see
Figure 26
.
Note:
The Input and Output modes for I2S are exclusive.
