pletronics普锐特为什么 TCXO 有削波的正弦波输出?FX532B-16.0000
大多数陶瓷 LCC 封装的 TCXO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。

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。
