SERVICE AIDS WARNING All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wrist wrap with resistance. Keep components and tools also at this potential.

Page 55 TDA7703/TDA7703R 5.0 FUNCTION DESCRIPTION 5.1 FM-Mixer The IMR mixer is optimized for optimum performance in case of a passive tuned prestage and for a passive fixed bandpass without tuning for low-cost application. The input frequency is downconverted to low IF with high image rejection. 5.2 FM - AGC The programmable RFAGC senses the mixer input, the IFAGC senses the IFADC input to avoid overload.
Page 56 TDA7703/TDA7703R 5.12 I C ADDRESS SELECTION / RDS INTERRUPT INTERFACE PIN As explained also in 5.13.1, there is one pin (RDSINT, pin 29) dedicated to selecting the I address of the device. In the TDA7703R only this pin serves the additional function of RDS interrupt output to communicate to the uP when a new RDS block is available.
Page 57 TDA7703/TDA7703R a chip address byte must be sent at the beginning of the transmission. The value can be C2 or C8 (according to the mode chosen at start-up during boot) for “write”; as many data bytes as one wants can follow the address before the communication is terminated.
