AM Tuners for Car Radios and Home Stereos
Overview
The LA1136N/NM and LA1137N/NM are high-performance
AM electronic tuner ICs offering sophisticated functions. They
are especially suited for use in car radio and home stereo
(antenna: loop) applications.

Features
.
Excellent cross modulation characteristic: Meets the
requirements for preventing not only adjacent-channel
interference but also interference caused by all channels
within broadcast band.
.
Narrow-band signal meter output: Usable as auto search stop
signal. Has linearity up to 100 dB.
.
Local oscillation buffer output: Facilitates designing of
electronic tuner system, frequency display, etc.
.
OSC (with ALC): Improves tracking error because
oscillation output is stabilized at a low level (350 mVrms:
LA1137N) for varactor diode.
.
MIX: Double-balanced differential MIX meeting the
requirements for preventing spurious interference, IF
interference.
.
Good characteristic at high input: 130 dB input
fm = 400 Hz 80%mod THD = 0.5% typ.
.
High S/N: Good S/N at medium input (55 dB typ).
.
Usable sensitivity: (S/N = 20 dB input): 25 dB
(when using 2SK715 )
.
VCC variation compensation: Less variation in gain,
distortion: 8 to 12 V
AM stereo capability (LA1136N only)
.
IF band switching circuit on chip; controlled by
microcontroller
.
Oscillating circuit for AM stereo; SUB S/N improved to
6dB
.
IF output for AM stereo decoder
.
Improved tweet characteristics: 10 dB increase, controlled by
microcontroller
.
Improved cross modulation characteristics, especially
sensitivity suppression characteristics: 15 dB improvement,
wide-band AGC operation even for SW band interference
.
Improved low-frequency modulation distortion
.
Improved temperature characteristics: S-meter, SD sensitivity
.
Faster RF AGC response: RF: 1/3; IF: 1/8 (compared to
predecessors)
.
Improved capability for driving external RF AGC transistors:
IB max = 200 A
.
Measures to prevent incorrect seek operation
.
IF count buffer on chip; controlled by microcontroller
.
Time constant switching circuit on chip for RF and IF
AGC
.
IF AGC clear circuit on chip
.
Measures that prevent stopping one station too soon
