Using Clipped Sine Waveform with Chipset having Input Buffer
使用具有输入缓冲器的芯片组的限幅正弦波形

•To convert the clipped sine waveform to a square waveform signal such as CMOS, an input buffer is necessary.
•要将限幅正弦波形转换为方形波形信号（如CMOS），需要输入缓冲区。
•Generally, ICs that TCXO’s output going into would have input buffer functionality integrated inside the chip. Oscillator circuit should have Rf feedback resistor connected in parallel with the inverter.
•通常，TCXO输出的IC将在芯片内部集成输入缓冲功能。 振荡器电路应具有与逆变器并联的Rf反馈电阻。
•If the IC does not have Rf resistor inside then an Rf resistor would need to be added externally between input pin and output pins of the inverter.
•如果IC内部没有Rf电阻，则需要在变频器的输入引脚和输出引脚之间添加一个Rf电阻。
•The external Rf resistor value shall be between 100K to 10M ohm.
•外部Rf电阻值应在100K至10M欧姆之间。
•Except for the 7x5mm product lines, a 1000 pF capacitor needs to be placed in series between the TCXO output pin and the IC clock input pin for all the other smaller form-factor TAITIEN TCXOs.
•除7x5mm产品系列外，对于所有其他更小尺寸的TAITIEN TCXO，需要在TCXO输出引脚和IC时钟输入引脚之间串联一个1000 pF电容。

Using Clipped Sine Waveform with Chipset without Input Buffer
在没有输入缓冲器的情况下使用带有芯片组的削波正弦波形

•If the IC does not have input buffer functionality incorporated, an inverter such as 74HC04 and an Rf resistor would need to be added in series between the output pin of the TCXO and the clock input pin of the IC to convert the clipped sine waveform to a square waveform
•如果IC没有内置输入缓冲器功能，则需要在TCXO的输出引脚和IC的时钟输入引脚之间串联一个74HC04和Rf电阻等反相器，以将限幅正弦波转换为方波
•The external Rf resistor value shall be between 100K to 10M ohm.

•TAITIEN TCXO with clipped sine wave output can also be used in conjunction with an oscillator IC to generate square wave output for the chip set.
•具有限幅正弦波输出的TAITIEN TCXO也可与振荡器IC配合使用，为芯片组生成方波输出。
•The output from TCXO needs to be connected to the crystal input pin on the oscillator IC and the output pin from the oscillator IC shall be connected to the input pin on the chip set.
•TCXO的输出需要连接到振荡器IC上的晶体输入引脚，振荡器IC的输出引脚应连接到芯片组的输入引脚。
