LA1193M

LA1193V

Overview

The LA1193M and LA1193V are front-end ICs developed for use in car radios. It incorporates an extremely wide dynamic

range mixer and a new AGC system consisting of a dual-system wide-band AGC and a new keyed AGC to provide

excellent interference suppression characteristics.

Features

• Improved interference characteristics

— Expanded mixer input dynamic range

Mixer input usable sensitivity : 15dB

µ

Mixer input I.M. QS :

90dB

µ

(The dynamic range has been increased by 6dB over the earlier LA1175M.)

— Development of a new wide-band AGC circuit

Improved interference characteristics for both nearchannel interference and far-channel interference Improved

interference characteristics for the TV band

— Development of a 3D-AGC system

The adjacent channel two-signal interference characteristics can be effectively improved without degrading the

strong-field three-signal interference characteristics during keyed AGC operation.

• Improved stability design

— AGC circuit local oscillator isolation

Measures were taken to prevent the deterioration of AMR, noise level, THD and other characteristics during AGC

operation.

— AGC circuit incorrect operation measures

The LA1193M provides methods to prevent incorrect operation due to local oscillator injection and loss of DC balance.

• Improved temperature characteristics

— Conversion gain

— AGC sensitivity

— Antenna damping drive output current
