NTE821 Integrated Circuit TV Chroma Demodulator
Description: Specifically designed to match advances in color picture tube phosphors, the NTE821 is a monolithic silicon integrated circuit in a 14–Lead DIP type package and consists of three output
amplifiers, a new resistor matrix, two double–balanced chroma demodulators, and a very stable bias circuit. When used with the NTE714 subcarrier regeneration system and the NTE715 chroma amplifier, this device completes the typical three–block chroma system. Alternatively, the NTE821 chroma demodulator can be used with the NTE738 chroma processor to form a complete two–block chroma system. The output
amplifiers are specifically designed to meet the low impedance, short–circuit protected driving requirements of high–level color output
amplifiers. Internal ripple filter
capacitors greatly reduce the high–frequency components of demodulation and thereby extend the output
voltage swing capability of the output stages and at the same time eliminates the need for external output filtering components. Features: D Output Short–Circuit Protection D Excellent Subcarrier Rejection D 600mV Maximum Offset
