PCM3002/3003
PCM AUDIO INTERFACE
The four-wire digital audio interface for PCM3002/3003 is
comprised of: LRCIN (pin 10), BCKIN (pin 11), DIN (pin
15), and DOUT (pin 12). The PCM3002 may be used with
any of the four input/output data formats (Formats 0 - 3),
while the PCM3003 may only be used with selected input/
output formats (Formats 0 - 1). For the PCM3002, these
formats are selected through PROGRAM REGISTER 3 in
the software mode. For the PCM3003, data formats are
selected by the 20BIT input (pin 16). Figures 2, 3 and 4
illustrate audio data input/output formats and timing.
The PCM3002/3003 can accept 32-, 48-, or 64-bit clocks
(BCKIN) in one clock of LRCIN. Only 16-bit data formats
can be selected when 32-bit clocks/LRCIN are applied.
