Notes:
[1]. The CMT2210LW can directly work with external reference clock input to XIN pin (a coupling capacitor is required) with
peak-to-peak amplitude of 0.3 to 0.7 V.
[2]. This is the total tolerance including (1) initial tolerance, (2) crystal loading, (3) aging, and (4) temperature dependence.
The acceptable crystal tolerance depends on RF frequency and channel spacing/bandwidth.
[3]. This parameter is to a large degree crystal dependent.
