TA8795BF

Description

Offered in a flat 60-pin plastic package, the TA8795BF is a multi-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.)
