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 performance 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.

FEATUREs:
• Small−sized Package
• Minimum Number of External Parts Required

VIF−SIF
• Excellent Buzz Beat Characteristics
• High−Gain VIF Amplifier Eliminating the need for a Preamplifier
• AGC Speed can be Increased
• Video/Audio Simultaneous Muting, or Audio−Only Muting Possible

Video−Chroma
• A Quadratic Differentiation Circuit allowing Soft Video Tone Operation is also Incorporated
• Adjustment−free Chroma Sync

Deflection
• Adjustment−free Horizontal, Vertical Sync
• Dual AFC System with Excellent Horizontal Noise Characteristics
• Vertical Sync Stabilizing Circuit which is Scarcely Affected by Motor Noise
