TA8795BF 产品说明VIDEO SIGNAL PROCESSOR IC FOR LCD TVsOffered in a flat 60-pin plastic package, the TA8795BF is amulti-system IC integrating video, chroma, and sync signal processor circuits for PAL, NTSC, and SECAM systems with B, G, M, and N variations. Such automatic signal detection functions as PAL / NTSC / SECAM chroma system detection, 4.43 / 3.58MHz subcarrier detection, and 50 / 60Hz vertical sync frequency detection make this IC ideal for processing the signals of portable LCD televisions designed to be used anywhere in the world. (Uses M / N PAL external detection.) FEATURESVideo circuitBrightness control, unicolor controlSecond-order differential sharpness control Black stretch circuit DC restoration adjustable circuit Demodulation output circuit YNR (coring) γ correction (two-point approximation) Chroma circuitColor control, tint controlAutomatic detection of PAL / NTSC / SECAM systems, system forced mode Automatic detection of 3.58 / 4.43MHz subcarrier frequency (M / N PAL detected externally) Direct PAL demodulation (without 1H delay line)  TA8795BF 产品现货订购热线： TA8795BF 产品 pdf datasheet(责任编辑：www.gongwin.com) |
