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.
