LA1193M
LA1193V
Monolithic Linear IC
For Car Radios
High-Performance FM Front End
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 : 15dBμ
Mixer input I.M. QS :
90dBμ
(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
