LA1193M

Ordering number : EN4715B 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 ...
