带内置热敏电阻的NX1210AC-76.8MHz-STD-CTR-1晶体单元的研制

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).

带内置热敏电阻的NX1210AC-76.8MHz-STD-CTR-1晶体单元的研制 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. 带内置热敏电阻的NX1210AC-76.8MHz-STD-CTR-1晶体单元的研制

带内置热敏电阻的NX1210AC-76.8MHz-STD-CTR-1晶体单元的研制

我们很高兴地通知您，Nihon Dempa Kogyo Co.，Ltd. 已为NX1210AC晶振（尺寸1.2×1.0×0.55mm）开发了一个内置热敏电阻的晶体单元（76.8MHz），并已开始样品发货。

随着移动通信向5G的转变，芯片组中使用的时钟源频率的增加，导致了对低相位噪声的需求不断增加。

特别地，为了适应毫米波等载波频率，需要增加内部乘法数。然而，增加乘法数会增加噪声分量，由于调制精度（信号相位和幅度转移）的降低，可能导致接收灵敏度和通信效率的降低。

为了通过减少乘法次数来提高相位噪声，需要将作为参考谐振器的晶体谐振器的频率从38.4MHz提高到76.8MHz。为了进一步降噪，除高频操作外，还需要提高驱动水平，保持高稳定的温度特性。

带内置热敏电阻的NX1210AC-76.8MHz-STD-CTR-1晶体单元的研制, 为了满足这些困难的需求，我们利用内部种植的高品质合成石英，利用先进的光刻加工技术，实现了一种紧凑、高频的产品。

该产品具有与NX1612SD_76.8MHz相同的特点，1210贴片石英晶振NX1612SD_76.8MHz首次获得高通技术智能手机芯片组（高通®骁龙690,750G和480）认证，正在量产，是一种小型化产品，安装面积减少到38%。

从2021年5月开始提供样品。（NDK零件号： EXS00A-CS10506）

5G智能手机市场正在迅速扩张，我们计划在扩大销售的同时确保该产品供应稳定。

我们将继续通过石英设备和水晶应用设备业务，为实现一个安全、安全、舒适的社会做出贡献。
