DESCRIPTIONS
Miscellaneous signals
GPCL
26
I/O
General-purpose control logic. This terminal has three functions:
1. General-purpose output. In this mode the state of GPCL is directly
programmed via the host port.
2. Vertical blank output. In this mode the GPCL terminal is used to indicate
the vertical blanking interval of the output video. The beginning and end
times of this signal are programmable via the host port control.
3. Sync lock control input. In this mode when GPCL is high, the output clock
frequencies and sync timing are forced to nominal values.
GLCO
31
I/O
This serial output carries color PLL information. A slave device can decode the
information to allow genlocking to the TVP5020. Data is transmitted at the SCLK
rate. Additionally, this terminal, in conjunction with PALI and FID, is used to
determine the host port mode configuration during initial power up.
OEB
62
I
Output enable for Y and UV terminals. Output enable is also controllable via the
host port.
