VIF & SIF Circuit for VCR
Description:
The NTE15001 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:
High–Gain VIF Amp Requiring No Preamp
High AGC Speed
Provides Wide–Band Detection Characteristics and Meets Sound MPX Demodulation Requirements
because of FM Detection being Quadrature Detection.
Possible to use Sound REC Pin (Pin2), AUX Pin (Pin3)
Possible to Mute Video, Sound for VCR
Pin7 GND: Muting of both Video and Sound
Pin29 GND: Muting of Sound Only
Functions:
VIF Section: VIF Amp Video Det, Peak IF AGC, B/W Noise–Canceller, RF AGC, AFT, SIF DET
SIF Section: SIF Limiter Amp, FM Det, DC ATT, AF Driver
