I²S Interface

A digital stereo input is available for a virtual Dolby source from an external decoder.

A digital stereo output (I²S compatible) is available for routing the demodulated signal or a

converted input audio signal into a Dolby Pro Logic Decoder or an external DAC. The STV82x6 I²S

interface drives the serial bus (SCK, WS, SDO) in Master mode in format 32.fs with a sampling

frequency (fS) of 32 kHz. An additional master clock (MCK) in format 256.fs (fS = 8.192 MHz) is

provided if required for the slave interface.

Both Philips and Sony modes are supported with programmable Word Selection (WS) polarity

(register I2S). By default, all I²S digital outputs are set in high impedance and must be switched to

low impedance via register CTRL before use.

A clock system output (SYSCK) is also available for clock peripherals using the same quartz

frequency as the STV82x6. By default, this clock output (identical to the crystal oscillator) is set to

high impedance and must be switched to low impedance via register CTRL before use.
