NTE7129
Integrated Circuit
IF Signal Processing (Super PLL−II VIF + SIF)
Circuit for TVs & VCRs
Description:
The NTE7129 is an intercarrier−type VIF + SIF integrated circuit in a 24−Lead DIP type package that
supports excellent sound and image quality. The pin assignment of the NTE7129 is identical to that
of the NTE7130, allowing the NTE7130 to be used for split systems while the NTE7129 is used for
intercarrier systems. In addition, the NTE7129 suppresses Nyaquist buzz interference by using a PLL
(Phase−Lock Loop) detection system with a buzz canceller in order to provide the best sound quality
possible.
Features:
D Excellent Buzz and Buzz−Beat Characteristics due to PLL
D Built−In APC Time Constant Switch
D Duplicate Time Constant System Suited for High−Speed AGC
D Excellent DG and DP Characteristics
D RF AGC Adjustment is Simple
