www.DataSheet4U.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. TC90A80N Features TV format: NTSC (3.58) Dynamic comb filter YNR circuit CNR circuit Luminance signal non-linear vertical edge corrector (with coring function) Luminance signal horizontal frequency characteristic corrector (with coring function) Luminance signal line noise canceller Record/playback input switch circuit (switches between Y/C and Y inputs) Y and C input pins, independently one another (Y: sync tip clamp; C: center bias) Re-mixer circuit after Y/C sharpness processing Skew detector and correctors (NTSC ×5 Mode: in units of 0.2 H) 8-bit 4 fsc AD converter (2 channels) 10-bit 8 fsc DA converter (2 channels) 1-H delay line (2 channels) I2C bus control I2C bus decode output pin (High/Low) 5-V single power operation Weight SDIP28-P-400-1.78 : 1.7 g (typ.)
