NTE1608 Integrated Circuit AM Tuner w/Electronic Tuning Description: The NTE1608 is a high performance integrated circuit in a 20–Lead DIP type package to be used as an AM electronic tuner. It provides an automatic search–stop signal, local oscillator buffer–output, and the low level local oscillation, as well as providing all other functions required of an AM tuner. Moreover, the stable local oscillation from LW to SW facilities the use of many bands. Functions: D RF Amplifier D IF Amplifier D MIX D AGC D OSC (with ALC) D Detection D Local Oscillation Buffer–Output D Signal Meter Driving Output (also used as an Automatic Search Stop–Signal). Features: D Narrow–Band Signal Meter: Available as an automatic search–stop signal (also available as a wide–band signal meter). Signal meter output = 1/2 frequency ± 1.5kHz typ. D Local Oscillation Buffer–Output:: Facilitates the design of electronic tuning systems and frequency representation. D OSC (with ALC): The oscillation output has been stabilized at a low level (350mVrms) for a varactor diode, and tracking error has been minimized. D RF Amplifier: Excellent in usable sensitivity by incorporating low–noise transistors in cascode circuit (45dB/m typ) D MIX: Double balanced differential MIX prevents the influence of spurious radiation and IF interferences (IF interference = 85dB typ) D Low Noise: Excellent in S/N for intermediate input (57dB typ). D Compensation for VCC Fluctuation: Allows little gain fluctuation and little distortion fluctuation (8 to 16V). D Low Shock Noise: Able to decrease the shock noise by selecting AGC time constant when changing VCC–on and/or switching the mode.
