The data and the signals correspond as listed in the tables. Since the external pins (MKSEL etc.) set by the serial
input are unused, applications must assure that these pins do not become floating. If initialization is performed, set
the initial values listed in the table.
5. Muting
A soft muting function is applied to the data if the MUTE pin (pin 40) is set high when data with a 32 or 48 kHz
sampling frequency is input. The input signal values are gradually attenuated so that the data reaches –
∞
1024/fs
(seconds) later. When the soft muting function is turned off, the amplitude becomes the same as that of the input
1024/fs (seconds) later.
For input data with a 44.1 sampling frequency, the data is forcibly set to 0 on the next rising edge of the LRCK
signal after the MUTE signal goes from low to high. Similarly, data is output on the next rising edge of the LRCK
signal after the MUTE signal goes from high to low.
6. Initialization
When power is first applied, the LSI must be initialized when the pin settings are changed. Initialization is performed
by holding INITB (pin 2) low for at least 1 μs in the state where the MCK1 signal is input after the power supply
voltage has stabilized.
