Active video indicator output/external clk input
When XTAL1 is used as a reference clock and this terminal is left unconnected, this
terminal is internally pulled down.
When XTAL1 is used as a reference clock and AVID output is required, this pin must be

connected to this terminal.
When XTAL 1 is connected to ground, CLK_IN may be connected to an external
single-ended oscillator from a 1.8-V to 3.3-V compatible clock signal depending on
IO_DVDD voltage.

GLCO: This serial output carries color PLL information. A slave device can decode the
information to allow chrominance frequency control from the TVP5151 decoder. Data is
transmitted at the SCLK rate in Genlock mode. In RTC mode, SCLK/4 is used.
