LRCIN
DIN
Sample Rate Clock Input. Controls the update rate (fs).
Serial Data Input. MSB first, right justified (Sony format,
18 bits) or I
2
S (Philips format, 16 or 18 bits).
Bit Clock Input. Clocks in the data present on DIN input.

BCKIN
Mode Control and Clock Signals
1
XTI
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.
A “HIGH” selects I
2
S input data format, and a “LOW”
selects Normal (Sony) input data format.
De-emphasis selection.
De-emphasis selection.
Soft Mute Control. When set “LOW”, the outputs are
muted.
Buffered Output of Oscillator. Equivalent to XTI.
Oscillator Output. When using the internal clock, tie to
the opposite side (from pin 1) of the crystal oscillator.
When using an external clock, leave XTO open.

ZERO
Infinite Zero Detection Flag, open drain output. When
the input is continuously zero for 65,536 cycles of
BCKIN, ZERO is “LOW”.
Resets DAC operation with an active “LOW” pulse.
