Figure 3-8: H, V, and F Input Timing
3.5 DVB-ASI Mode
The GS9092A enters DVB-ASI mode when the application layer sets the DVB_ASI
pin HIGH.
In this mode, all SMPTE processing functions are disabled, and the 8-bit transport
stream data will be 8b/10b encoded prior to serialization.
3.5.1 Control Signal Inputs
In DVB-ASI mode, the DIN9 and DIN8 will be configured as DVB-ASI control
signals INSSYNCIN and K_IN respectively.
When INSSYNCIN is set HIGH, the device will insert K28.5 sync characters into
the data stream. This function is used to assist system implementations where the
GS9092A's internal FIFO is disabled (FIFO_EN = LOW), and the device is
preceded by an external FIFO. Parallel data may be clocked into the external FIFO
at some rate less than 27MHz. The INSSYNCIN input may then be connected to
the FIFO empty signal, thus providing a means of padding up the data transmission
rate to 27MHz.
NOTE 1: If the internal FIFO is enabled (FIFO_EN = HIGH), the INSSYNCIN pin
should be grounded (see
DVB-ASI Mode on page 24
).
NOTE 2: In DVB-ASI mode, 8b/10b encoding will take place after K28.5 sync
character insertion.
K_IN should be set HIGH whenever the parallel data input is to be interpreted as
any special character (including the K28.5 sync character), defined by the
DVB-ASI standard. This pin should be set LOW when the input is to be interpreted
as data.
