NTSC, PAL, and DTV (480i and 480p) inputs
YCbCr signals conform to the CCIR 601 standard.
The YC C signal is a multiplexed CbCr signal.
PC input (up to XGA)
Three independent systems for both horizontal
and vertical sync signals
Any input polarity may be used. The LC74981W
discriminates internally.
Positive logic (active-high) input
A composite signal can be input to BLKIH.
(BLKIV must be tied high in this case.)
Three independent input systems
Fixed frequency crystal oscillator (65 MHz maximum)

For each RGB signal: 6 bits and 2 phases
Also provides single-phase output (In this mode
the odd pixel pins are used for output.)
The sync period, position, and polarity can be set.
A composite sync signal can be output from VOUT.
Outputs the same frequency as that of the crystal
oscillator.
The enable period and the polarity can be set.
A composite signal can be output from BLKVOUT.
Outputs a frequency 1/2 that of the crystal
oscillator.
