3.3.1 Video Mode
The internal FIFO is in video mode under the following conditions:
the FIFO_EN and IOPROC_EN pins are set HIGH,
the FIFO_MODE[1:0] bits in the IOPROC_DISABLE register (
Table 3-4
) are
configured to 00b,
the DETECT_TRS pin is set LOW; and
TRS insertion, EDH correction/insertion, illegal code re-mapping, and SMPTE
packet insertion are all disabled (i.e. bits 0, 2, 3, and 4 of the
IOPROC_DISABLE register are set HIGH).
NOTE: The FIFO will still enter video mode if any of bits 0, 2, 3, or 4 of the
IOPROC_DISABLE register are LOW; however, the output video data will contain
errors.
By default, the FIFO_MODE[1:0] bits are set to 00b by the device whenever the
SMPTE_BYPASS pin is set HIGH and the DVB_ASI and DETECT_TRS pins are
set LOW.
In video mode, the H, V, and F pins become input signals that must be supplied by
the user.
Figure 3-2
shows the input and output signals of the FIFO when it is configured for
video mode.
Figure 3-2: FIFO in Video Mode
When operating in video mode, the GS9092A will read data sequentially from the
FIFO, starting with the first active pixel in location zero of the memory. In this mode,
it is possible to use the FIFO for clock phase interchange and data delay.
The device will ensure read-side synchronization is maintained, according to the
supplied PCLK and supplied H, V, and F timing information.
Full write-control of the FIFO is made available to the application interface such
that data is clocked into the FIFO on the rising edge of the externally provided
WR_CLK. The FIFO write pointer will be reset to position zero of the memory when
there is a HIGH-to-LOW transition at the WR_RESET pin.
