Over a broad temperature range, an AT performs very well and much easier to
compensate electronically. It is also a simpler crystal to manufacture than a SC
cut device. For applications where a stability of a few ppm is acceptable, a TCXO
can be a cost-effective alternative.
The SC cut results in a much higher Q device and achieves much lower phase
noise than the AT cut. The device is also more sensitive to pressure and
temperature variation and is mounted in temperature controlled hermetic
chamber.
OCXO oven temperature is in the range of 90°C. The devices heat-up and
become stable within ~ 5 minutes.
