KVG石英晶体的结晶形成XMP-7135-5E-18pF-20MHz
石英作为矿物是所有类型石英谐振器,石英滤波器和石英振荡器的原料。大部分地壳由天然石英构成,其纯粹形式也称为深石英或α石英。石英是由硅和氧原子构成的完美对称的理想晶格。这种晶格使石英具有重要的特性,即当对晶体施加机械压力时,可以在石英晶振晶体的两端测量电压。同样,当从外部施加电压时,晶体会变形。这种行为使其成为在电路中以振动夸克的形式使用的理想原材料。以前在石英的生产中使用矿物开采石英,山水晶,现在几乎完全使用人工制造的石英,其纯度极高。例如,在每只腕表(石英表)中,一小块石英材料确保秒针每秒可靠且始终向前滑动一次。

Silicon EFM32TG210 MCU是便携式心脏监护仪
“首先,ADC提供分辨率和滤波选项,以确保他们能够获得所需的原始数据采集,同时保持在功耗预算范围内。其次,与其他架构相比,EFM32TG微控制器的电源管理可显著节省功耗。凭借极快的睡眠和唤醒转换、外设的自动操作和低功耗时钟生成,EFM32TG超出了系统要求,使用标准CR1225电池可实现长达14天的连续ECG记录。硅实验室的布莱恩·布鲁姆解释道。Gabriel还指出,贴片晶振,EFM32TG210的性能和功耗模式允许他们按照规格设计和构建CAM补丁,并最终实现预期的结果。他坚持认为,在设计设备时,拥有满足性能预期的MCU是保持项目进度和预算的关键。“EFM32架构非常出色,仅用48 mAh CR1225电池就可以进行长达14天的完整披露记录。被捕获的信号可以低至150uVpp,即使在这个范围内,模拟波形的细节也能保持清晰。EFM32架构包含高性能ADC,可以捕捉这些细节,同时保持电磁安静的辐射特性,使小细节不会受到干扰的阻碍。集成过采样和异常稳定且可配置的ADC特性是救命稻草。EFM32架构在当时绝对是革命性的,大多数芯片供应商仍在追赶。"

微晶RV-3032-C7使RTC更小更高效
微晶银斯沃琪集团旗下的一家公司与CSEM合作开发了一款特别小且节能的RTC,名为RV-3032-C7。RV-3032-C7背后的驱动力是微型晶体与智能电子设备的结合,功耗极低。
利用实时时钟实现节能,使RTC更小更高效,RV-3032-C7时钟晶体振荡器提供多种可编程和自动计时功能,但其最重要的功能是其热补偿晶体频率,这意味着它可以在-40°C至105°C的温度范围内提供精确稳定的计时。相比之下,未进行温度补偿并在这些温度下工作的RTC每年可能会偏离一小时。彼得曼32.768K有源晶振的优势,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.
不断精进自我的优质制造商彼得曼公司,致力于开发大量高质量的产品,随着近几年来,现代计量应用的时间要求大幅提高。现代计量应用的通常要求是7年后时间偏移1小时。应用的工作温度范围也应符合该值。最多1小时。7年后对应于32,768kHz下16ppm绝对值的频率容差。传统的32,768 kHz振荡晶体不再可能满足这些要求。彼得曼32.768K有源晶振的优势.
一方面,这是因为32,768kHz仅在+25°C时具有10ppm的频率容差,另一方面,在-40/+85°C温度范围内的温度稳定性高于-180ppm。此外,老化约。计算精度时,必须考虑10年后的30ppm。最差情况下,32.768K有源晶振的最大频率稳定性为+40/-220 ppm(包括+25°C时的调整、温度稳定性和10年后的老化)。外部电路电容必须能够补偿由要同步的ic振荡器级的内部电容和杂散电容引起的任何系统频率偏移。为32,768晶振选择无外部电路电容的布局包含很大的风险,因为在批量生产期间,32,768晶振的精度既不能校正也不能调整以适应突然变化的PCB条件。最初,32,768英寸晶体的交叉角度是为手表的最佳精度而设计的,而不是为如今使用它的大多数应用而设计的。
