NTE15001
Integrated Circuit
VIF & SIF Circuit for VCR
Description:
The NTE15001 is an integrated circuit in a 30鈥揕ead 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鈥揼rade
type according to the designer鈥檚 policy.
Features:
D
High鈥揋ain VIF Amp Requiring No Preamp
D
High AGC Speed
D
Provides Wide鈥揃and 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鈥揅anceller, RF AGC, AFT, SIF DET
D
SIF Section: SIF Limiter Amp, FM Det, DC ATT, AF Driver
