TA1383AFG
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA1383AFG
NTSC Chroma Decoder, Multi-Point Scan Sync Processor,
H/V Frequency Counter IC for Color TV
TA1383AFG integrates an NTSC chroma decoder, multi-point
scan sync processor (equivalent to pin D4), and H/V frequency
counter in a 30-pin flat package. The IC is ideal for double scan
TVs.
The baseband signal processing block incorporates sub
adjustment circuits and a RGB/Y color difference matrix. The
sync processor block supports 525I/P, 750P, and 1125I.
TA1383AFG incorporates the I²C bus. The device can control
various functions via the bus line.
