Appendix B
Following items are important to get highest performance of TDA7512 in application:
1.
2.
3.
4.
5.
6.
7.
In order to avoid leakage current from PLL loop filter input to ground a guardring is
recommended around loop filter PIN’s with PLL reference voltage potential.
Distance between Crystal and VCO input PIN18 should be far as possible and Crystal
package should get a shield versus ground.
Blocking of VCO supply should be near at PIN16 and PIN17.
Wire length to FM mixer1 input and output should be symmetrically and short.
FM demodulator capacitance at PIN44 should be sense connected as short as
possible versus demodulator ground at PIN47.
With respect to THD capacitive coupling from PIN20 to VCO should be avoided.
Capacitance at PIN20 has be connected versus VCC2 ground.
Wire length from AM mixer tank output to 9 kHz ceramic filter input has to be short as
possible.
