NTE1728 Integrated Circuit VIF & SIF Circuit for VCR
Description: The NTE1728 is an integrated circuit in a 30-Lead DIP type package containing the VIF section and SIF on a single chip. Since this device is capable of performing video detection and sound detection independently or simultaneously, it can be applied to various sets from popular type to high-grade type according to the designer's policy. Features: D High-Gain VIF Amp Requiring No Preamp D High AGC Speed D Provides Wide-Band Detection Characteristics and Meets Sound MPX Demodulation Requirements because of FM Detection being Quadrature Detection. D Possible to use Sound REC Pin (Pin2), AUX Pin (Pin3) D Possible to Mute Video, Sound for VCR D Pin7 GND: Muting of both Video and Sound D Pin29 GND: Muting of Sound Only Functions: D VIF Section: VIF Amp Video Det, Peak IF AGC, B/W Noise-Canceller, RF AGC, AFT, SIF DET D SIF Section: SIF Limiter Amp, FM Det, DC ATT, AF Driver Operating Characteristics: (TA = +25C, VCC = 12V, fp = 58.75MHz, fs = 54.25MHz (VIF), fo = 4.5MHz (SIF) unless otherwise specified)
