Can a similar crystal and not exactly the one on the datasheet be used on RF 433 receiver?
In the datasheet there's this formula:
Fosc = Frf / (32 + 1.198/12)
OFFICIAL QUARTZ CRYSTAL:
When using the official quartz crystal you get a carrier frequency of 433.92 Mz
13.51783 MHz = (433.92 / (32 + 1.198/12))  MHz
UNOFFICIAL QUARTZ CRYSTAL:
When using the unofficial quartz crystal you get a carrier frequency of 433,9967 MHz
You are off of by 70 KHz and the receiver might go blind.
