Hi Sir,
does crystal have specification requirement?
The specifications of the crystal we used are 25MHz, +/-10ppm, DL 150uW, ESR<110ohm
the crystal to adjust capacitor NC(C537), tolerence -6.5 ~ -9.5 ppm, does this meet the requirement? thanks.

Tommy,
This looks suitable. Be sure to follow the guidelines laid out in 9.4.1 Crystal Input (XIN) Interface for avoiding load capacitance mismatch to reduce frequency error.
Thanks,
