为什么TCXO有削波的正弦波输出?

为什么TCXO有削波的正弦波输出?

大多数陶瓷LCC封装的TCXO温补晶振仅提供削波正弦波输出。这样做的原因有很多,尽管它让许多想要CMOS输出电平的电路设计人员感到沮丧。

* CMOS输出会显着增加TCXO IC的功耗。IC和封装中产生的温度梯度将限制实现最佳TCXO补偿的能力。

* 由于内部热梯度导致TCXO不符合规格,可能的CMOS负载范围很广会改变补偿设计。

* 当输出电平改变时,CMOS输出会导致电源和接地瞬变。这种噪声会对TCXO的相位噪声性能产生不利影响。

* CMOS输出会产生更大的EMI/RFI信号,这可能会导致难以满足美国FCC和其他国家最终系统的辐射能量限制。削波的正弦波,既是低幅度又主要是正弦波,导致低信号电平和更少的谐波。

* 使用这些TCXO的许多应用都有ASIC输入,可以接受削波正弦波并在内部转换为CMOS逻辑电平。
