FAQ
Q1: What is SC-cut and AT-cut?
A: SC-cut and AT-cut refer to two different types of crystal cuts used in quartz crystal oscillators, each with distinct characteristics:
SC-cut
1)Designed to minimize frequency shifts caused by thermal stress during rapid temperature changes.
2)Offers superior frequency stability over a wide temperature range and low phase noise.
3)Ideal for high-precision applications like OCXOs (Oven-Controlled Oscillators) and aerospace systems.
4)Performs well under harsh conditions (e.g., vibration, shock).
AT-cut
1)The most common crystal cut, widely used in standard oscillators (e.g., TCXOs, VCXOs).
2)Provides good frequency stability for moderate temperature ranges but is more sensitive to thermal stress than SC-cut.
3)Cost-effective and suitable for consumer electronics, telecommunications, and industrial devices.
Q2: What's the difference between them?
A: 1) Thermal Performance: SC-cut excels in environments with rapid temperature fluctuations; AT-cut is more affordable but less stable under thermal stress.
2)Applications: SC-cut is preferred for high-reliability systems (e.g., military, aerospace), while AT-cut dominates commercial and general-purpose use.
3)Cost: SC-cut crystals are more expensive due to complex manufacturing; AT-cut offers a balance of performance and cost.
