Description

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 TC90A80N/F  IC incorporates skew correctors for special playback. The IC is then suitable for processing S-VHS recorded playback signals.
