Overview
The LA1177 is an FM front end IC for use in car radio,
home stereo applications. It requires fewer external parts.
The on-chip oscillator and oscillation buffer facilitate
designing of electronic tuning sets.
Features
Wide-band AGC circuit (Improvement in intermodu-
lation, cross modulation characteristics).
On-chip local oscillation buffer (For electronic tuning).
Functions
Oscillator, oscillation buffer.
Mixer.
Wide-band AGC circuit.
IF amplifier.
