KA2198BD
RGB ENCODER FOR PAL/NTSC
RGB ENCODER FOR PAL/NTSC
The KA2198BD is a monolithic circuit designed for RGB
encoder of video system. This device provides encoding
system of PAL and NTSC video signal. The KA2198BD
contains matrix of R-Y/B-Y, modulator, pulse generator,
regulator, built in BPF of chroma and delay line of lumin-
ance, Y/C output using S-VHS system. It is suitable for
video equipment.
