LA1193M

LA1193V

Overview

Features

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.

• Improved interference characteristics

• Improved stability design

• Improved temperature characteristics

— Expanded mixer input dynamic range

— Development of a new wide-band AGC circuit

— Development of a 3D-AGC system

— AGC circuit local oscillator isolation

— AGC circuit incorrect operation measures

— Conversion gain

— AGC sensitivity

— Antenna damping drive output current

Mixer input usable sensitivity : 15dBµ

Mixer input I.M. QS :

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

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

interference characteristics for the TV band

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

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

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

operation.

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