Notes
1. In the TDA8373 and TDA8377 pin 35 (4.43 MHz crystal) is internally connected and pin 33 is just a subcarrier output
which can be used as a reference signal for comb filter ICs.
2. In the TDA8373 and TDA8374 the following pins are different (SDIP56): Pin 27: not connected; Pin 45: AVL
capacitor.
