I want to build an oscillator using IC MM5369 with output frequency 50Hz. I read the datasheet of the IC and I found the circuit that I don't know. The circuit is attached at port 5 and 6 from the IC. The question are :
1. What the function of this circuit?
2. What will happen if I change the value of the
a. crystal (the capacitors and resistors are not
b. capacitors (the others are not changed)?
c. resistors (the others are not changed)?
3. If I want to make 50Hz output frequency, how do I
calculate the value of the crystal that I must use?

Thank you for advanced

Best Regards
