NTE1608
Integrated Circuit
AM Tuner w/Electronic Tuning
Description:
The NTE1608 is a high performance integrated circuit in a 20âLead DIP type package to be used as
an AM electronic tuner. It provides an automatic searchâstop signal, local oscillator bufferâoutput,
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 BufferâOutput
D Signal Meter Driving Output (also used as an Automatic Search StopâSignal).
Features:
D NarrowâBand Signal Meter: Available as an automatic searchâstop signal (also available as
a wideâband signal meter). Signal meter output = 1/2 frequency ± 1.5kHz typ.
D Local Oscillation BufferâOutput:: 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 lowânoise 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 VCCâon and/or switching the mode.
