TC90A44P,45P/F TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TC90A44P,TC90A45P,TC90A45F NTSC 2-LINE DIGITAL Y / C SEPARATION IC The TC90A44P, TC90A45P / F separates luminance (Y) and chrominance (C) signals from NTSC system composite video signal by using 2 horizontal (H) lines separation. The Y / C separation unit for TV and VCR set is able to assembled at low cost, because it requires few external parts and no adjustment.
