3.2.1 Parallel Input in SMPTE Mode
When the device is operating in SMPTE mode (see
SMPTE Mode on page 32
), SD
data is presented to the input bus in 10-bit multiplexed format. The input data
format must be word aligned, multiplexed luma and chroma data.
NOTE: When operating the device in an 8-bit SMPTE system, the 2 LSBs
(DIN [1:0]) must be set to 0.
3.2.2 Parallel Input in DVB-ASI Mode
When operating in DVB-ASI mode (see
DVB-ASI Mode on page 33
), the device will
accept 8-bit data words on DIN[7:0] such that DIN7 = HIN is the most significant bit
of the encoded transport stream data and DIN0 = AIN is the least significant bit.
In addition, DIN9 and DIN8 will be configured as the DVB-ASI control signals
INSSYNCIN and K_IN respectively. See
Control Signal Inputs on page 33
for a
description of these DVB-ASI specific input signals.
3.2.3 Parallel Input in Data-Through Mode
When operating in Data-Through mode (see
Data-Through Mode on page 34
), the
GS9092A passes data presented to the parallel input bus to the serial output
without performing any encoding, scrambling, or word-alignment.
3.2.4 I/O Buffers
The parallel data bus, status signal outputs, and control signal input pins are all
connected to high-impedance buffers. These buffers use either +1.8V or +3.3V
DC, supplied at the IO_VDD and IO_GND pins. For a +3.3V tolerant I/O, the
IO_VDD pins can be connected to either +1.8V or +3.3V. For a +5V tolerant I/O,
the IO_VDD pins must be supplied with +3.3V.
While RESET is LOW, STAT output pins are muted and all other output pins
become high impedance.
