NIPPON PRECISION CIRCUITS—15
Audio Data Output (DOL, DOR, BCKO,
WCKO, OW20N)
The output data is in serial, simultaneous left and
right-channel, 2s complement, MSB first, BCKO
burst (NPC format) format. The output data word
length is selected by the state of OW1N and OW2N
as shown in table 5.
8fs serial data is output in sync with the falling edge
of the internal system clock and BCKO clock. The
output timing is determined by CKSLN and the out-
put word length. When CKSLN is LOW, the output
timing is the same for different output word lengths.
Only the number of BCKO bit clock pulses word
changes depending on the output word length
selected. When CKSLN is HIGH, however, the out-
put timing for 24-bit output mode starts 1 bit earlier
than for 18/20/22-bit output mode.
