NTE7015
Integrated Circuit
PLL SIF & VIF for TV & VCR
Description:
The NTE7015 is a semiconductor integrated circuit consisting of an IF signal processor suitable for color TV
sets and VTRs with AV.
The circuits include VIF amplifiers, video detector, VCO, APC detector, AFT, video equalizer, IF/RF AGC, SIF
detector functions.
Features:
D Employment of a full synchronous detector circuit using PLL as video detector provides excellent DG,
DP, 920kHz beat and cross color characteristics.
D Usage of PLL−SPLIT method to obtain intercarrier by separating video IF and audio IF processing by
VCO output provides good sound sensitivity and reduces buzz. In consumer sets, intercarrier is also
available from the video detector output.
D Built−in video equalizer suitable for VTRs and color TV sets equipped with video output terminals.
D Employment of quadrature detector circuit for FM detection of audio IF requires no adjustment.
Applications:
TV sets, VTR tuners
