2.7.2 VBI Raw Data Output
The TVP5147 decoder can output raw A/D video data at twice the sampling rate for external VBI slicing. This
is transmitted as an ancillary data block, although somewhat differently from the way the sliced VBI data is
transmitted in the FIFO format as described in Section 2.7.1. The samples are transmitted during the active
portion of the line. VBI raw data uses ITU-R BT.656 format having only luma data. The chroma samples are
replaced by luma samples. The TVP5147 decoder inserts a four-byte preamble 000h 3FFh 3FFh 180h before
data start. There are no checksum bytes and fill bytes in this mode.

Reset and Initialization
Reset is initiated at power up or any time terminal 34 (RESETB) is brought low. Table 29 describes the status
of the TVP5147 terminals during and immediately after reset.

Figure 224. Reset Timing
The TVP5147 requires that pin 69 (C_1/GPIO) be held LOW. If using the 20-/16-bit mode or using this pin as
GPIO, then this pin must be pulled low through a 2.2-k
pulldown resistor (see Figure 51). If unused, this
pin can be shorted to ground. (Note: If using the 20-/16-bit mode and only using the 16 MSBs, it is possible
to short pin 69 to GND, but the current for IOVDD will increase by 2 or 3 mA.)
