Figure 8. Audio Data Output Timing
dedicated output pins for both professional and consumer applications
The DIR1701 has parallel output pins for both professional and consumer applications. In professional mode
de-emphasis flag EMFLG indicates a 50/15-
μ
s time constant pre-emphasis. Professional mode is set when Bit
0 of CSBIT Byte 0 is HIGH. When Bits 2 to 4 of CSBIT Byte 0 is 110, the EMFLG becomes HIGH. In other cases,
EMFLG is LOW. Audio/non-audio flag ADFLG indicates S/PDIF data mode, i.e., Bit 1 of CSBIT Byte 0. When
ADFLG is LOW, S/PDIF data includes PCM audio signal. In other cases, ADFLG is HIGH.
In consumer mode EMFLG indicates 2-channel audio with a 50/15-
μ
s time constant pre-emphasis. Consumer
mode is set when Bit 0 of CSBIT Byte 0 is LOW. When Bits 3 to 5 of CSBIT Byte 0 is 100, EMFLG becomes
HIGH. In other cases, EMFLG is LOW. The ADFLG signal indicates whether S/PDIF includes digital data, such
as AC-3 or not. When Bit 1 of CSBIT Byte 0 is HIGH, the incoming S/PDIF includes non-audio signal. In other
cases, ADFLG is LOW.
These dedicated output pins are checked for only L-ch CS information. The DIR1701 does not support CRC
check function in professional mode. As for other flags, CS bit and user-bit for professional and consumer
applications, are directly supplied by serial mode at CSBIT (pin 15) and URBIT (pin 16). These pins indicate
L-ch and R-ch information sequentially.
