The FM (de)modulator and peak noise reduction functions are highly integrated, resulting in few external components and no external adjustments. In addition special functions for audio mixing, dubbing and descrambling have been implemented. PACKAGE TYPE NUMBER NAME TDA9614H Note 1. When using IR reflow soldering it is recommended that the Drypack instructions in the “Quality Reference Handbook” (order number 9398 510 63011) are followed.
