TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8795BF
VIDEO SIGNAL PROCESSOR IC FOR LCD TVs
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.)
