com TC90A80N/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC90A80N,TC90A80F 3-Line Digital Comb Filter for VCR, YNR/CNR, and Skew Correctors (NTSC) The TC90A80N/F is a 3-line digital Y/C (luminance/ chrominance) separation IC for VCR.
In addition to YNR and CNR used for noise reduction in the playback signal, the IC incorporates skew correctors for special playback.
The IC is then suitable for processing S-VHS recorded playback signals.
