Description
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.
