TA8795BF
TENTATIVE 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.)
FEATURES
Video circuit
l Brightness control, unicolor control
l Second-order differential sharpness control
l Black stretch circuit
l DC restoration adjustable circuit
l Demodulation output circuit
l YNR (coring)
l γ correction (two-point approximation)
Chroma circuit
l Color control, tint control
l Automatic detection of PAL / NTSC / SECAM
systems, system forced mode
l Automatic detection of 3.58 / 4.43MHz subcarrier
frequency (M / N PAL detected externally)
l Direct PAL demodulation (without 1H delay line)
Weight: 0.8g (Typ.)
Sync circuit
l Auto slice sync separator circuit
l Countdown horizontal oscillator circuit
l Automatic detection of 50 / 60Hz vertical sync
frequency
l Sync separation output
Demodulation output circuit
l Selectable output between RGB and YUV
