I need tuning Crystal 13.5725MHz ---> 13.2 MHz

Help me

Hello Luvu,

Your request is practicaly inposible ~2.3% working frequency . It is too wide range for any type of quarz crystal units. You have to change your solutions with alternative like PLL or DDs are.

XTASA

I agree, you can not tune a crystal that far. Typically 200 ppm, maybe 1000 ppm if you really try hard.

The same crystal will have different series and parallel resonant frequencies. Maybe you can change the circuit topology and use the other mode and get closer to the frequency you need?
