NTE1863
Integrated Circuit
Single−Chip Signal Processor for Color TV
Description:
The NTE1863 is a single−chip integrated circuit in a 42−Lead DIP type package and incorporates a
circuit to process all types of signals (VIF, SIF, video, chroma, deflection) for color TVs based on the
NTSC system. In designing this device, its basic characteristics including synchronization perfor-
mance are greatly improved, and taking into consideration its needed application in AV equipment
such as VCRs, the necessity of adjustment is substantially reduced. A simple, compact color TV can
be implemented by simply connecting a tuner, power supply, and output circuit to the NTE1863.
When using the NTE1863 in conjunction with vertical output−use IC NTE1855, only one connection
(vertical timing pulse) is required, with no connection required for feedback, thus simplifying layout
of printed circuit pattern.
