3.11.2 Parallel Output in SMPTE Mode
When the device is operating in SMPTE mode, Section 3.7 on page 30, data may
be presented to the output bus in either multiplexed or demultiplexed form
depending on the setting of the 20bit/10bit input pin.
In 20-bit mode, (20bit/10bit = HIGH), the output data will be word aligned,
demultiplexed luma and chroma data. Luma words will always appear on
DOUT[19:10] while chroma words will occupy DOUT[9:0].
In 10-bit mode, (20bit/10bit = LOW), the output data will be word aligned,
multiplexed luma and chroma data. The data will be presented on DOUT[19:10],
and the device will force DOUT[9:0] LOW.
3.11.3 Parallel Output in DVB-ASI Mode
When operating in DVB-ASI mode, Section 3.8 on page 34, the GS9060
automatically configures the output port for 10-bit operation regardless of the
setting of the 20bit/10bit pin.
The extracted 8-bit data words will be presented on DOUT[17:10] such that
DOUT17 = HOUT is the most significant bit of the decoded transport stream data
and DOUT10 = AOUT is the least significant bit.
In addition, DOUT19 and DOUT18 will be configured as the DVB-ASI status
signals SYNCOUT and WORDERR respectively. See Section 3.8.3 on page 35 for
a description of these DVB-ASI specific output signals.
DOUT[9:0] will be forced LOW when the GS9060 is operating in DVB-ASI mode.
3.11.4 Parallel Output in Data-Through Mode
When operating in Data-Through mode, Section 3.9 on page 36, the GS9060
presents data to the output data bus without performing any decoding,
descrambling or word-alignment.
