NJW1300B
SIGNAL PROCESSOR FOR COLOR TFT
s
GENERAL DESCRIPTION
The NJW1300B
is a color TFT signal processor which
include color signal modulator , count down circuit , RGB
demodulator , RGB interface , and common pole driver ,
required by color TFT signal processing after Y/C separator.
It corresponds broadcasting systems of both NTSC and
PAL , because it can select the down (1/525 or 1/625) by
the internal switch.
The NJW1300B
is suitable for TFT LCD panel and car
navigation systems.
