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.
When operating in DVB-ASI mode, (see
GS1559 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
page 41
DOUT[9:0] will be forced LOW when the GS1559 is operating in DVB-ASI mode.
When operating in Data-Through mode, (see
GS1559 presents data to the output data bus without performing any decoding,
descrambling or word-alignment.
