Figure 4-1: PCLK to Data Timing
4.2.1 Parallel Input in SMPTE Mode
When the device is operating in SMPTE mode, see
SMPTE Mode on page 25
, both
SD and HD data may be presented to the input 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 input data format should be word aligned,
demultiplexed luma and chroma data. Luma words should be presented to
DIN[19:10] while chroma words should occupy DIN[9:0].
In 10-bit mode, (20bit/10bit = LOW), the input data format should be word aligned,
multiplexed luma and chroma data. The data should be presented to DIN[19:10].
DIN[9:0] will be high impedance in this mode.
4.2.2 Parallel Input in DVB-ASI Mode
When operating in DVB-ASI mode, see
DVB-ASI mode on page 27
, the GS1531
automatically configures the input port for 10-bit operation regardless of the setting
of the 20bit/10bit pin.
The device will accept 8-bit data words on DIN[17:10] such that DIN17 = HIN is the
most significant bit of the encoded transport stream data and DIN10 = AIN is the
least significant bit.
In addition, DIN19 and DIN18 will be configured as the DVB-ASI control signals
INSSYNCIN and KIN respectively. See
DVB-ASI mode on page 27
for a
description of these DVB-ASI specific input signals.
DIN[9:0] will be high impedance when the GS1531 is operating in DVB-ASI mode.
4.2.3 Parallel Input in Data-Through Mode
When operating in Data-Through mode, see
Data-Through Mode on page 28
, the
GS1531 passes data presented to the parallel input bus to the serial output without
performing any encoding or scrambling.
The input data bus width accepted by the device in this mode is controlled by the
setting of the 20bit/10bit pin.
