Sample Rate Clock Input. Controls the update rate (fs).
Serial Data Input. MSB first, right justified format contains a frame of 16-bit or 20-bit data.
Bit Clock Input. Clocks in the data present on DIN input.
Buffered Output of Oscillator. Equivalent to fs.
Oscillator Input (External Clock Input). For an internal clock, tie XTI to one side of the crystal oscillator. For an external clock,
tie XTI to the output of the chosen external clock.
Oscillator Output. When using the internal clock, tie to the opposite side (from pin 5) of the crystal oscillator. When using an
external clock, leave XTO open.
Operation Mode Select. For serial mode, tie MODE “High”. For parallel mode, tie MODE “Low”.
Mute Control. To disable soft mute, tie MUTE “High”. To enable soft mute, tie MUTE “Low”.
Mode Control for Data/De-emphasis. See “Mode Control Functions” on page 10.
Mode Control for BCKIN/De-emphasis. See “Mode Control Functions” on page 10.
Mode Control for WDCK/Double speed dubbing. See “Mode Control Functions” on page 10.
