PAL/NTSC 1 CHIP FOR C/TV
PAL/NTSC 1 CHIP IC FOR COLOR
TELEVISION
The KA2161 combines an IF system and a video/chroma/deflection
on a monolithic integrated circuit to provide a PAL/NTSC color te-
levision.
This device is suitable to a muiti-CTV svstem on a 54 SDIP and
includes VI F/SIF, videc/chroma/deflection processor.
54-SDIP-600
