2.17 Genlock Control and RTC
A Genlock control (GLCO) function is provided to support a standard video encoder to synchronize its internal color
oscillator for properly reproduced color with unstable timebase sources like VCRs.
The frequency control word of the internal color subcarrier digital control oscillator (DTO) and the subcarrier phase
reset bit are transmitted via terminal 23 (GLCO). The frequency control word is a 23-bit binary number. The frequency
of the DTO can be calculated from the following equation:
dto
ctrl
sclk
F
=
x
23
2
where Fdto is the frequency of the DTO, Fctrl is the 23-bit DTO frequency control, and Fsclk is the frequency of the
SCLK.
2.17.1 TVP5150A Genlock Control Interface
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 7 SCLKs after the transmission of the
last bit of DCO frequency control. Upon the transmission of the reset bit, the phase of the TVP5150A 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 26 shows the timing diagram of the GLCO mode.
