KVG石英晶體的結晶形成XMP-7135-5E-18pF-20MHz
石英作為礦物是所有類型石英諧振器,石英濾波器和石英振蕩器的原料。大部分地殼由天然石英構成,其純粹形式也稱為深石英或α石英。石英是由硅和氧原子構成的完美對稱的理想晶格。這種晶格使石英具有重要的特性,即當對晶體施加機械壓力時,可以在石英晶振晶體的兩端測量電壓。同樣,當從外部施加電壓時,晶體會變形。這種行為使其成為在電路中以振動夸克的形式使用的理想原材料。以前在石英的生產中使用礦物開采石英,山水晶,現在幾乎完全使用人工制造的石英,其純度極高。例如,在每只腕表(石英表)中,一小塊石英材料確保秒針每秒可靠且始終向前滑動一次。

Silicon EFM32TG210 MCU是便攜式心臟監護儀
“首先,ADC提供分辨率和濾波選項,以確保他們能夠獲得所需的原始數據采集,同時保持在功耗預算范圍內。其次,與其他架構相比,EFM32TG微控制器的電源管理可顯著節省功耗。憑借極快的睡眠和喚醒轉換、外設的自動操作和低功耗時鐘生成,EFM32TG超出了系統要求,使用標準CR1225電池可實現長達14天的連續ECG記錄。硅實驗室的布萊恩·布魯姆解釋道。Gabriel還指出,貼片晶振,EFM32TG210的性能和功耗模式允許他們按照規格設計和構建CAM補丁,并最終實現預期的結果。他堅持認為,在設計設備時,擁有滿足性能預期的MCU是保持項目進度和預算的關鍵。“EFM32架構非常出色,僅用48 mAh CR1225電池就可以進行長達14天的完整披露記錄。被捕獲的信號可以低至150uVpp,即使在這個范圍內,模擬波形的細節也能保持清晰。EFM32架構包含高性能ADC,可以捕捉這些細節,同時保持電磁安靜的輻射特性,使小細節不會受到干擾的阻礙。集成過采樣和異常穩定且可配置的ADC特性是救命稻草。EFM32架構在當時絕對是革命性的,大多數芯片供應商仍在追趕。"

微晶RV-3032-C7使RTC更小更高效
微晶銀斯沃琪集團旗下的一家公司與CSEM合作開發了一款特別小且節能的RTC,名為RV-3032-C7。RV-3032-C7背后的驅動力是微型晶體與智能電子設備的結合,功耗極低。
利用實時時鐘實現節能,使RTC更小更高效,RV-3032-C7時鐘晶體振蕩器提供多種可編程和自動計時功能,但其最重要的功能是其熱補償晶體頻率,這意味著它可以在-40°C至105°C的溫度范圍內提供精確穩定的計時。相比之下,未進行溫度補償并在這些溫度下工作的RTC每年可能會偏離一小時。彼得曼32.768K有源晶振的優勢,Time requirements in modern metering applications have massively increased in the last few years. The usual requirement in modern metering applications is a time offset of 1 hour after 7 years. It should also be possible for the operating temperature range of the application to comply with this value. 1 hour max. after 7 years corresponds to a frequency tolerance of ±16 ppm absolute at 32,768 kHz. It is no longer possible for conventional 32,768 kHz oscillating crystals to meet these requirements.
On the one hand, this is because 32,768 kHz are only available with a frequency tolerance of ±10ppm at +25°C, on the other hand, the temperature stability over a temperature range of -40/+85°C is more then -180 ppm. Moreover, ageing of approx. ±30 ppm after 10 years must be taken into account when calculating accuracy. In the worst case, a 32,768 kHz crystal has a maximum frequency stability of +40/-220 ppm (including adjustment at +25°C, temperature stability and ageing after 10 years). External circuit capacitance must be able to compensate any systematic frequency offset caused by the internal capacitance of the oscillator stage of the IC to be synchronised and by stray capacitance. The selection of a layout without external circuit capacitance for the 32,768 crystal involves a great risk because the accuracy of the 32,768 crystal can neither be corrected nor adjusted to suddenly changing PCB conditions during series production. Initially, the intersection angle for the 32,768 crystal was designed for optimal accuracy in wristwatches, and not for most of the applications for which it is used nowadays.
In order to meet the highly accurate time requirements, we as a clocking specialist offer the series ULPPO ultra low power 32,768 kHz oscillator. This oscillator can be operated with each voltage within a VDD range of 1.5 to 3.63 VDC. The specified current consumption is 0.99 µA. The temperature stability of ULPPOs is ±5 ppm over a temperature range of -40/+85°C. Frequency stability (delivery accuracy plus temperature stability) is ±10 ppm, and ageing after 20 years is ±2 ppm. Thus the maximum overall stability of ULPPOs is ±12 ppm including the ageing after 10 years. These are industry best parameters.
No external circuit capacitance is required for the circuiting of the ultra small housing (housing area: 1.2 mm2). The input stage of the IC installed in the ULPPO independently filters the supply voltage. Compared to crystals, ULPPOs save a lot of space on the printed circuit board so that the packing density can be increased, and smaller printed circuit boards can be designed. The adjustment of the amplitude further reduces the power consumption of the ULPPO.
For space calculations, both external circuit capacitances for a crystal on the printed circuit board must also be taken into account. With its two external circuit capacitances, even the smallest 32,768 kHz crystal requires more space on the PCB than ULPPOs do.
Moreover, very small 32,768 kHz crystals have very high resistances which usually cannot be safely overcome by the oscillator stages to be synchronised because the oscillator stages of the ICs or RTCs to be synchronised have very high tolerances as well. Therefore, sudden response time problems in the field might occur which can be ruled out with ULPPOs. Thus, the safe operation of the application is possible with ULPPOs under all circumstances.
Oscillator stages consume a lot of energy to keep a 32,768 crystal oscillating. Usually, the input stage of the MCU can be directly circuited with the LVCMOS signal of the ULPPO (usually Xin). Thus the input stage of the MCU can be deactivated (bypass function) so that the energy saved can be used for the calculation of the system power consumption of the meter. Moreover, ULPPOs are able to synchronise several ICs at a time. Due to the very high accuracy of the ULPPO, less time synchronisations are required, which also saves system power.
Of course, ULPPOs can be used in any applications which require miniaturised ultra low power 32,768 kHz oscillators such as smartphones, tablets, GPS, fitness watches, health and wellness applications, wireless keyboards, timing systems, timing applications, wearables, IoT, home automation, etc. Due to the high degree of accuracy of 32,768 kHz oscillators, the standby time or even the hypernation time in hypernation technology applications can be significantly increased so that a high amount of system power can be saved due to the significantly lower battery-intensive synchronisation cycles. Thus the 32,768 kHz oscillator is the better choice compared to 32,768 kHz crystals. Ultra low power 32,768 kHz oscillators are available with diverse accuracy variations – see also the ULPO-RB1 and -RB2 series.
不斷精進自我的優質制造商彼得曼公司,致力于開發大量高質量的產品,隨著近幾年來,現代計量應用的時間要求大幅提高?,F代計量應用的通常要求是7年后時間偏移1小時。應用的工作溫度范圍也應符合該值。最多1小時。7年后對應于32,768kHz下16ppm絕對值的頻率容差。傳統的32,768 kHz振蕩晶體不再可能滿足這些要求。彼得曼32.768K有源晶振的優勢.
一方面,這是因為32,768kHz僅在+25°C時具有10ppm的頻率容差,另一方面,在-40/+85°C溫度范圍內的溫度穩定性高于-180ppm。此外,老化約。計算精度時,必須考慮10年后的30ppm。最差情況下,32.768K有源晶振的最大頻率穩定性為+40/-220 ppm(包括+25°C時的調整、溫度穩定性和10年后的老化)。外部電路電容必須能夠補償由要同步的ic振蕩器級的內部電容和雜散電容引起的任何系統頻率偏移。為32,768晶振選擇無外部電路電容的布局包含很大的風險,因為在批量生產期間,32,768晶振的精度既不能校正也不能調整以適應突然變化的PCB條件。最初,32,768英寸晶體的交叉角度是為手表的最佳精度而設計的,而不是為如今使用它的大多數應用而設計的。
