AM/FM 1CHIP TUNER WITH PLL
1. Recommend using filter with 330
2. Output gain of RF mixer is fixed by both of 330
10.7MHz IF filter. Thereafter to control output gain of mixer depends on changing load register on PIN 34, which
case both of input impedance of IF filter and load register are recommended to have same impedance.
3. Application of a input pin CE, DI, CL depends on the output of Micro-processor(Figure. 19). Input pin of CE,
CL, DI must be set to be VDD using R1 and R2 In the case of Figure.19 <B>.
4. Crystal can be selectable among 75kHz, 3.6MHz, 7.2MHz, 10.8MHz. The connection must be the same as
Figure. 20 to share crystal for Micro-processor
