Hi,
My customers have a question about the crystal matching of TRF7962A.
They are doing crystal matching test.
They tried C1 and C2 with two patterns, 22pF and 27pF.
In general, frequency will increase when the capacitance is small.
However actually measured, when the capacitance was small, the frequency became small.
In general, if the capacitance is small, the negative resistance will be large. However, when the capacitance was small, the negative resistance became small.
Customers can't decide C1 and C2 because it is different from the general behavior.
Does anyone know anything about this behavior of TRF7962A?
Regards,
Rei
