Summary：

1.Excellent power-on characteristics: Since the thermal overshoot of a SC-cut resonator is about 2 orders of magnitude smaller than an AT-cut, the SC-cut crystal oscillator can quickly reach its frequency stability after powering up. In general, the stability can reach 2×10-9 after powering up for 6 minutes. 2.Low aging: The stress effect of the SC-cut resonator is small and the aging caused by stress relaxation is also small. The aging rate can reach 10-11/d. 3.Outstanding short-term frequency stability: After the drive level is increased, the signal-to-noise ratio relative to the white noise is increased, thus the far-end phase noise can be improved. Currently, the highest level can reach -160~-170 dBc/hz.
