NTE1863 Integrated Circuit Single-Chip Signal Processor Color
Description: NTE1863 single-chip integrated circuit 42-Lead type package incorporates circuit process types signals (VIF, SIF, video, chroma, deflection) color based NTSC system. designing this device, basic characteristics including synchronization performance greatly improved, taking into consideration needed application equipment such VCRs, necessity adjustment substantially reduced. simple, compact color implemented simply connecting tuner, power supply, output circuit NTE1863. When using NTE1863 conjunction with vertical output-use NTE1855, only connection (vertical timing pulse) required, with connection required feedback, thus simplifying layout printed circuit pattern. Features: Small-sized Package Minimum Number External Parts Required VIF-SIF Excellent Buzz Beat Characteristics High-Gain Amplifier Eliminating need Preamplifier Speed Increased Video/Audio Simultaneous Muting, Audio-Only Muting Possible Video-Chroma Quadratic Differentiation Circuit allowing Soft Video Tone Operation also Incorporated Adjustment-free Chroma Sync Deflection Adjustment-free Horizontal, Vertical Sync Dual System with Excellent Horizontal Noise Characteristics Vertical Sync Stabilizing Circuit which Scarcely Affected Motor Noise Absolute Maximum Ratings: +25°C unless otherwise specified) Supply Voltage, V9max, V11max Supply Current, I20max 16mA Allowable Power Dissipation +65°C), Pdmax 1.3W Operating Temperature Range, Topr -10° +65°C Storage Temperature Range, Tstg -55° +125°C Circuit Current, I36max -6mA I4max -3mA Input Current (Peak Current), I21max I19max 10mA
