2 DESCRIPTION
The TDA7338 is a new concept of monolithic inte-
grated stereo decoder with noise blanking for FM
car radio applications. With the used BICMOS
technique, the 19KHz Notch Filter, the PLL Filter
and Phase Filter is realized on the chip with a
Switched Capacitor concept. Avoiding the use of
multipliers and non linear circuits a very high per-
formance in terms of noise suppression and total
harmonic distortion is
