Hardware Mode 1 Description (DEFAULT Data Flow, AES3 Input)
Hardware Mode 1 data flow is shown in Figure 24. Audio data is input via the AES3 receiver, and rate con-
verted. The audio data at the new rate is then output both via the serial audio output port and via the AES3
transmitter.
The channel status data, user data and validity bit information are handled in four alternative modes: 1A and
1B, determined by a start-up resistor on the COPY pin. In mode 1A, the received PRO, COPY, ORIG, EM-
PH, and AUDIO channel status bits are output on pins. The transmitted channel status bits are copied from
the received channel status data, and the transmitted U and V bits are 0.
In mode 1B, only the COPY and ORIG pins are output, and reflect the received channel status data. The
transmitted channel status bits, user data and validity bits are input serially via the PRO/C, EMPH/U and
AUDIO/V pins. Figure 20 shows the timing requirements.
Start-up options are shown in Table 8, and allow choice of the serial audio output port as a master or slave,
choice of four serial audio output port formats, and the source for transmitted C, U and V data. The following
pages contain the detailed pin descriptions for Hardware mode 1.
If a validity, parity, bi-phase, or lock receiver error occurs, the current audio sample will be held.
