Real-Time Control (RTC)
Although the TVP5147 decoder is a line-locked system, the color burst information is used to determine
accurately the color subcarrier frequency and phase. This ensures proper operation with nonstandard video
signals that do not follow exactly the required frequency multiple between color subcarrier frequency and video
line frequency. The frequency control word of the internal color subcarrier PLL and the subcarrier reset bit are
transmitted via terminal 37 (GLCO) for optional use in an end system (for example, by a video encoder). The
frequency control word is a 23-bit binary number. The instantaneous frequency of the color subcarrier can be
calculated using the following equation:
F
PLL +
F
ctrl
223
F
sclk
where FPLL is the frequency of the subcarrier PLL, Fctrl is the 23-bit PLL frequency control word, and Fsclk is
two times the pixel frequency. This information can be generated on the GLCO terminal. Figure 217 shows
the detailed timing diagram.

NOTE:
RTC reset bit (R) is active-low, Sequence bit (S) PAL: 1 = (R-Y) line normal, 0 = (R-Y) line inverted, NTSC: 1 = no change

Output Formatter
The output formatter sets how the data is formatted for output on the TVP5147 output buses. Table 21 shows
the available output modes.
