The instantaneous frequency of the color subcarrier can be calculated from the following
equation:
F
PLL
+
F
ctrl

F
sclk
where F
PLL
is the frequency of the subcarrier PLL, F
ctrl
is the 23-bit PLL frequency control word,
and F
sclk
is two times the pixel frequency. Figure 2−19 shows the detailed timing diagram.

2.5 Output Formatter
The output formatter sets how the data is formatted for output on the TVP5146 output buses.
Table 2−1 shows the available output modes.
