32-MHz Crystal Oscillator

PARAMETERMINTYPMAXUNITCONDITION
Crystal frequency31.2532 33.6MHzIt is expected that there will be degraded sensitivity at multiples of XOSC/2 in RX, and an increase in spurious emissions when the RF channel is close to multiples of XOSC in TX. We recommend that the RF channel is kept RX_BW/2 away from XOSC/2 in RX, and that the level of spurious emissions be evaluated if the RF channel is closer than 1 MHz to multiples of XOSC in TX.
