帶內(nèi)置熱敏電阻的NX1210AC-76.8MHz-STD-CTR-1晶體單元的研制

We are pleased to inform you that Nihon Dempa Kogyo Co., Ltd. has developed a crystal unit (76.8MHz) with a built-in thermistor for NX1210AC (1.2×1.0×0.55mm-size) and has started sample shipment.

With the shift to 5G of mobile communications, the increasing frequency of clock sources used in chipsets has resulted in an increasing demand for low phase noise.

In particular, in order to accommodate carrier frequencies such as millimeter waves, it is necessary to increase the internal multiplication number. However, increasing the multiplication number increases the noise component, which may lead to reduce the reception sensitivity and communication efficiency due to degradation of modulation accuracy (signal phase and amplitude shift).

帶內(nèi)置熱敏電阻的NX1210AC-76.8MHz-STD-CTR-1晶體單元的研制 To improve phase noise by reducing the number of multiplications, it is required to increase the frequency of the crystal resonator as the reference oscillator from 38.4MHz to 76.8MHz. In order to achieve further noise reduction, it is also necessary to increase the drive level and maintain high stable temperature characteristics in addition to high-frequency operation.

To meet these difficult demands, we have realized a compact, high-frequency products by using high-quality synthetic quartz grown in-house and processing crystal blank with high precision using our won photolithography processing technology.

This product has the same characteristic as the NDK CRYSTAL NX1612SD_76.8MHz, which has obtained the first certification for Qualcomm Technologies smartphone chipset (Qualcomm® SnapdragonTM690, 750G and 480) which is under mass production, and it is a miniaturized product with a mounting area reduced to 38%.

Began supplying samples in May 2021. (NDK part number:EXS00A-CS10506)

The smartphone market for 5G is rapidly expanding, and we plan to work to ensure stable supplies of this product while expanding sales.

We will continue to contribute to the realization of a safe, secure and comfortable society through our quartz device and crystal application equipment businesses. 帶內(nèi)置熱敏電阻的NX1210AC-76.8MHz-STD-CTR-1晶體單元的研制

帶內(nèi)置熱敏電阻的NX1210AC-76.8MHz-STD-CTR-1晶體單元的研制

我們很高興地通知您，Nihon Dempa Kogyo Co.，Ltd. 已為NX1210AC晶振（尺寸1.2×1.0×0.55mm）開發(fā)了一個內(nèi)置熱敏電阻的晶體單元（76.8MHz），并已開始樣品發(fā)貨。

隨著移動通信向5G的轉(zhuǎn)變，芯片組中使用的時鐘源頻率的增加，導(dǎo)致了對低相位噪聲的需求不斷增加。

特別地，為了適應(yīng)毫米波等載波頻率，需要增加內(nèi)部乘法數(shù)。然而，增加乘法數(shù)會增加噪聲分量，由于調(diào)制精度（信號相位和幅度轉(zhuǎn)移）的降低，可能導(dǎo)致接收靈敏度和通信效率的降低。

為了通過減少乘法次數(shù)來提高相位噪聲，需要將作為參考諧振器的晶體諧振器的頻率從38.4MHz提高到76.8MHz。為了進(jìn)一步降噪，除高頻操作外，還需要提高驅(qū)動水平，保持高穩(wěn)定的溫度特性。

帶內(nèi)置熱敏電阻的NX1210AC-76.8MHz-STD-CTR-1晶體單元的研制, 為了滿足這些困難的需求，我們利用內(nèi)部種植的高品質(zhì)合成石英，利用先進(jìn)的光刻加工技術(shù)，實(shí)現(xiàn)了一種緊湊、高頻的產(chǎn)品。

該產(chǎn)品具有與NX1612SD_76.8MHz相同的特點(diǎn)，1210貼片石英晶振NX1612SD_76.8MHz首次獲得高通技術(shù)智能手機(jī)芯片組（高通®驍龍690,750G和480）認(rèn)證，正在量產(chǎn)，是一種小型化產(chǎn)品，安裝面積減少到38%。

從2021年5月開始提供樣品。（NDK零件號： EXS00A-CS10506）

5G智能手機(jī)市場正在迅速擴(kuò)張，我們計(jì)劃在擴(kuò)大銷售的同時確保該產(chǎn)品供應(yīng)穩(wěn)定。

我們將繼續(xù)通過石英設(shè)備和水晶應(yīng)用設(shè)備業(yè)務(wù)，為實(shí)現(xiàn)一個安全、安全、舒適的社會做出貢獻(xiàn)。
