A write of 1 to bit 4 of the chrominance control register at I2C subaddress 1Ah causes the subcarrier DTO
phase reset bit to be sent on the next scan line on GLCO. The active-low reset bit occurs seven SCLKs
after the transmission of the last bit of DCO frequency control. Upon the transmission of the reset bit, the
phase of the TVP5150AM1 internal subcarrier DCO is reset to zero.
A Genlock slave device can be connected to the GLCO terminal and uses the information on GLCO to
synchronize its internal color phase DCO to achieve clean line and color lock.
Figure 3-6 shows the timing diagram of the GLCO mode.
Figure 3-6. GLCO Timing
Figure 3-7 shows the timing diagram of the RTC mode. Clock rate for the RTC mode is four times slower
than the GLCO clock rate. For 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.
