AUDIO OUTPUT INTERFACE
The audio output interface includes BCKO (pin 26), WCKO
(pin 25), DOL (pin 24), and DOR (pin 23).
BCKO is the output bit clock and is used to clock data into
an audio D/A converter, such as the PCM1704. DOL and
DOR are the left and right audio data outputs. WCKO is the
output word clock and is used to latch audio data words into
an audio D/A converter.
WCKO runs at a fixed rate of 8f
S
(8X oversampling) for all
system clock rates.
BCKO is fixed at 256f
S
for system clock rates of 256f
S
or
512f
S
.
BCKO is fixed at 192f
S
for system clock rates of 384f
S
or
768f
S
.
The output data format used by the DF1704 for DOL and
DOR is Binary Two’s Complement, MSB-first, right-justi-
fied audio data. Figures 6(a) and 6(b) show the output data
formats for the DF1704. Figure 7 shows the audio output
timing.
MODE CONTROL
The DF1704 may be configured using either software or
hardware control. The selection is made using the MODE
input (pin 10).
