Fast blanking input
The fast blanking pin (FBLK) is TTL compatible. When it is at high level, the input signal is blanked
and replaced by OSD insets defined by binary levels on three OSD inputs and a dedicated OSD
contrast adjustment stage.
Blanking input
The blanking input BLK is TTL compatible. The active level is either high (positive pulse polarity) or
low (negative pulse polarity). When the level is active, the RGB outputs are at infra-black level,
regardless of the input level. The pulse on the BLK input defines the timing of the internal OCL
signal and it can also define the timing of the internal BPCP pulse. See
