KA2197D
RGB ENCODER FOR NTSC
RGB ENCODER
The KA2197 is a monolithic integrated circuit designed
for RGB encoder of video system. This device contains
matrix of R-Y/B-Y, modulator, pulse generator, regulator
and built in BPF of chroma and delay line of luminance
and Y/C output using S-VHS system.
The KA2197D is suitable for video equipment.
