EXTERNAL DIGITAL FILTER
INTERFACE AND TIMING
The PCM1738 supports an external digital-filter interface
comprised of a 4-wire synchronous serial port that allows
the use of an external digital filter. External filters include
the DF1704 and DF1706 from Texas Instruments, the
Pacific Microsonics PMD200, or a programmable digital
signal processor.
The 4-wire interface includes WCK as the word clock, BCK as
the bit clock, DATAL as the L-channel data, and DATAR as
the R-channel data. The external digital-filter interface is se-
lected using the DFTH bit of Control Register 20, which
functions to bypass the internal digital-filter portion of the
PCM1738. The 4-wire serial port is assigned to WDCK (pin 4),
BCK (pin 6), DATAL (pin 5), and DATAR (pin 15).
FIGURE 6. Serial Control Format.
NOTE: B15 is used for the selection of Write or Read. Setting W/R = 0 indicates a Write, while W/R = 1 indicates a Read.
B14 to B8 are used for register address.
B7 to B0 are used for register data.
DSD (DIRECT STREAM DIGITAL) FORMAT
INTERFACE AND TIMING
The PCM1738 supports a DSD format interface operation
that includes out-of-band noise filtering using an internal
Analog FIR filter. For DSD operation, pin 7 is redefined as
BCK, which operates at 64 x 44.1kHz; pin 5 is redefined as
DATAL (left-channel audio data), and pin 15 becomes
DATAR (right-channel audio data). Pins 4 and 6 must be
forced LOW in DSD mode. This configuration allows for
direct interface to a DSD decoder for SACD applications.
Detailed information for the DSD mode is provided in the
DSD Mode Operation section of this data sheet.
