PCM3000/3001
PCM AUDIO INTERFACE
The three-wire digital audio interface for PCM3000/3001 is
on LRCIN (Pin 16), BCKIN (Pin 17), DIN (Pin 18), and
DOUT (Pin 19). The PCM3000/3001 can operate with
seven different data formats. For the PCM3000, these for-
mats are selected through PROGRAM REGISTER 3 in the
software mode. For PCM3001, data formats are selected by
pin-strapping the three format pins. Figures 2, 3 and 4
illustrate audio data input/output format and timing.
PCM3000/3001 can accept 32, 48, or 64 bit clocks (BCKIN)
in one clock of LRCIN. Only formats 0, 2, and 6 can be
selected when 32 bit clocks/LRCIN are applied.
