Hardware Mode 3 Description
(Transceive Data Flow, with SRC)
Hardware Mode 3 data flow is shown in Figure 26. Audio data is input via the AES3 receiver, and rate con-
verted. The audio data at the new rate is then output via the serial audio output port. Different audio data,
synchronous to OMCK, may be input into the serial audio input port, and output via the AES3 transmitter.
The channel status data, user data, and validity bit information are handled in two alternative modes: 3A
and 3B, determined by a start-up resistor on the COPY pin. In mode 3A, the received PRO, COPY, ORIG,
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 zero.
In mode 3B, 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.
The serial audio input port is always a slave.
If a validity, parity, bi-phase, or lock receiver error occurs, the current audio sample will be held.
Start-up options are shown in Table 12, and allow choice of the serial audio output port as a master or slave,
whether TCBL is an input or an output, the serial audio ports formats, and the source of the transmitted C,
U, and V data. The following pages contain the detailed pin descriptions for Hardware mode 3.
