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.
