3.17.2 RTC Mode
Figure 3-10 shows the timing diagram of the RTC mode. Clock rate for the RTC mode is four times slower
than the GLCO clock rate. For Color PLL frequency control, the upper 22 bits are used. Each frequency
control bit is two clock cycles long. The active-low reset bit occurs six CLKs after the transmission of the
last bit of PLL frequency control.

3.18 Reset and Power Down
The RESETB and PDN terminals work together to put the TVP5150AM1 decoder into one of the two
modes. Table 3-8 shows the configuration.
After power-up, the device is in an unknown state with its outputs undefined, until it receives a RESETB
signal as depicted in Figure 3-11. After RESETB is released, the data (YOUT0 to YOUT7) and sync
(HSYNC, VSYNC/PALI) outputs are in high-impedance state until the TVP5150AM1 is initialized and the
outputs are activated.
NOTE
I
2C SCL and SDA signals must not change state until the TVP5150AM1 reset sequence has
been completed.
