- 比CMOS輸出更好的相位噪聲性能

Using Clipped Sine Waveform with Chipset having Input Buffer
使用具有輸入緩沖器的芯片組的限幅正弦波形

•To convert the clipped sine waveform to a square waveform signal such as CMOS, an input buffer is necessary.
•要將限幅正弦波形轉(zhuǎn)換為方形波形信號(hào)（如CMOS），需要輸入緩沖區(qū)。
•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輸出的IC將在芯片內(nèi)部集成輸入緩沖功能。 振蕩器電路應(yīng)具有與逆變器并聯(lián)的Rf反饋電阻。
•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內(nèi)部沒(méi)有Rf電阻，則需要在變頻器的輸入引腳和輸出引腳之間添加一個(gè)Rf電阻。
•The external Rf resistor value shall be between 100K to 10M ohm.
•外部Rf電阻值應(yīng)在100K至10M歐姆之間。
•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產(chǎn)品系列外，對(duì)于所有其他更小尺寸的TAITIEN TCXO，需要在TCXO輸出引腳和IC時(shí)鐘輸入引腳之間串聯(lián)一個(gè)1000 pF電容。

Using Clipped Sine Waveform with Chipset without Input Buffer
在沒(méi)有輸入緩沖器的情況下使用帶有芯片組的削波正弦波形

•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沒(méi)有內(nèi)置輸入緩沖器功能，則需要在TCXO的輸出引腳和IC的時(shí)鐘輸入引腳之間串聯(lián)一個(gè)74HC04和Rf電阻等反相器，以將限幅正弦波轉(zhuǎn)換為方波
•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.
•具有限幅正弦波輸出的TAITIEN TCXO也可與振蕩器IC配合使用，為芯片組生成方波輸出。
•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的輸出需要連接到振蕩器IC上的晶體輸入引腳，振蕩器IC的輸出引腳應(yīng)連接到芯片組的輸入引腳。
•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.
