NTE1604
Integrated Circuit
FM IF System for Car Radio
Description:
The NTE1604 is an integrated circuit in a 16-Lead SIP type package designed for use in FM car stereo receivers. This device features versatile muting characteristics and allows receiver designers to realize the muting performance according to their design concept.
Functions:
IF Amplification/Limiter
AFC Output
Muting Bandwidth
Quadrature Detector
Signal Meter Output
Muting Under Weak Signal Strength
AF Preamplifier
AGC Output
Features:
Versatile Mutings
a. When Muting Operation is Performed under a Weak Signal Strength, an Attenuation Slope
of the Audio Output Against the Input Signal Strength Varaitions can be Set at any Given
value
b. Maximum Muting Attenuation can be Selected Between about 6dB to 40dB
c. Input Signal Strength level which Actuates the Muting Circuit can be Set Freely
High Limiting Sensitivity (25dbµ Typ. with Muting OFF) Provides a Fine Quieting Characteristic
High Signal-to-Noise Ratio: 78dB Typ
Low Distortion (0.05% Typ) Available, if used with Double-Tuned Circuits
Good AM Rejection Ratio (63dB with 6 Stages of Differential IF Amplifiers)
Signal Meter Drive Output Proportional to the Input Signal Strength in dB
Clamped (±VBE) AFC Output, Bandwidth Adjustable
Delayed AGC Output for Front End Circuit
