... X 3. Separation setting mothod The LA3335M is so designed that the sub-signal gain is approximately 1.25 times as high as the main signal gain. The separation can be set by attenuating the sub-signal of the FM detection output. (See Figure Output impedance The value of capacitor Co depends on the attenuation of the sub-signal of the FM detection output and the IF IC output impedance Ro ...
