IDT艾迪悌有源晶体振荡器性能介绍

IDT艾迪悌有源晶体振荡器性能介绍，IDT公司作为行业的佼佼者，除了能够针对不同的用户需求给出完美的解决方案之外，还具备快速交付的能力，以及灵活多变的选择空间，正是因为选择空间的广泛，使得每一位用户都能在IDT公司找到自身所需的产品，随着行业的快速发展，对于成长型的IDT公司而言，有源晶振产品的局限化也影响公司的发展，为了突破目前的限制，利用自身的资源，打磨大量优质的产品。

这低功耗、低成本硅时钟振荡器我们的产品系列配备了最先进的IC技术，并在性能、超长寿命(MTBF 10亿小时)、出色的抗冲击和抗振动性、尺寸、精度、抖动、功耗和灵活性方面树立了标准。与其它硅振荡器一样，我们的SMD硅振荡器系列和相应的汽车版(AEC-Q100)使用硅谐振器同步IC。由于微硅谐振器的振动能量非常低，SMD硅振荡器的性能远远优于类似的石英振荡器。一般来说，SMD硅时钟振荡器可用于所有需要高性价比时钟振荡器的应用。

SMD硅振荡器的趋势持续快速增长。一方面，考虑到它们的性能，它们具有成本效益，可以取代石英振荡器，但以下情况除外TCXOs和VC-TCXOs，在所有垂直市场和应用中。另一方面，32.768kHz和MHz的超低功耗SMD振荡器可实现高达50%的系统节能——请咨询我们的专家，这是如何实现的。

新开发的推荐版本:

对于新开发产品，我们建议开发人员采用2.0×1.6mm或最大2.5×2.0mm尺寸的版本，具有2.25–3.63 VDC(-文章描述中的XX-)的宽电源电压范围，频率稳定性为20 ppm @-40/+85°C、30 ppm @-40/+105°C、30ppm @-40/+125°C或50ppm @-55/+125°C，以及对于引脚1的功能，我们建议使用待机功能，即使不一定需要该功能。原因:一方面，与潜在的成本节约相比，引脚#1的布线要求非常低，因为我们通常有大量的备用功能库存，这使得短期内以非常好的价格交货成为可能。在引脚1处没有待机功能的振荡器按要求的数量制造，这通常要贵得多。如果所需的振荡器没有库存，标准交付周期，包括定制产品，最长为4-6周。

SMD硅有源晶体振荡器具有所谓的软电平功能。详细信息可在以下报告中找到:“SMD硅时钟振荡器如何改善EMC–EMI”

SoftLevel功能无需额外费用，可以缩短输出信号的上升/下降时间。这使得输出信号的边缘更圆；在最慢的版本中，输出信号类似鲨鱼鳍。上升/下降时间延长达45%，第11次谐波的EMC衰减超过–60 dB。对于t这样一个简单的改编来说，这是一个巨大的价值升高和t秋天.

Thelow-power, low-cost silicon clock oscillatorsfrom our product range are equipped with state-of-the-art IC technology and set the standard in terms of performance, extreme longevity (MTBF 1 billion hours), excellent shock and vibration resistance, size, precision, jitter, power consumption and flexibility. As with other silicon oscillators, our SMD silicon oscillators of theseries and the correspondingautomotive versions (AEC-Q100)use a silicon resonator for synchronising the IC. Due to the very low vibration energy of the micro-silicon resonator, the performance of the SMD silicon oscillators is by far superior to the one of comparable quartz oscillators. Generally, the SMD silicon clock oscillators can be used in all applications where a very cost-efficient clock oscillator is required. Samples can normally be shipped on the same day, if they are requested before 2pm.

The trend towards SMD silicon oscillators continuous to grow rapidly. On the one hand, they are cost-efficient considering their performance and replace quartz oscillators, with the exception ofTCXOsandVC-TCXOs, in all vertical markets and applications. On the other hand, the ultra-low power of 32,768 kHz and MHz oscillators allow up to 50% system energy savings – ask our specialist how this is possible.

RECOMMENDED VERSION FOR NEW DEVELOPMENTS:

For new developments, we suggest to developers versions in the 2.0×1.6 mm or maximum in the 2.5×2.0 mm case, with a very wide supply voltage range of 2.25 – 3.63 VDC (-XX- in the article description), a frequency stability of ±20ppm@-40/+85°C, ±30ppm@-40/+105°C, ±30ppm@-40/+125°C, or ±50ppm@-55/+125°C, with the frequency of their choice. For the function of pin 1, we recommend using the standby function, even if this function is not necessarily required. Reason: On the one hand, the wiring requirements of pin #1 are very low in relation to the potential cost saving, Since we normally have large quantities with the standby function in stock, which makes short-term delivery at a very good price possible. Oscillators without standby function at pin 1 are manufactured in the required quantity, which is normally significantly more expensive. In the event that the required oscillator is not in stock, the standard delivery period, also for customised products, is 4 – 6 weeks maximum.

HOW THE EMC BEHAVIOUR CAN BE IMPROVED WITHOUT ADDITIONAL COSTS

The SMD silicon clock oscillators are equipped with the so-called SoftLevel function. Detailed information can be found in the following report:“How SMD silicon clock oscillator improves EMC – EMI”

The SoftLevel function is available at no extra cost and allows to reduce the rise/fall time of the output signal. This makes the edges of the output signal rounder; in the slowest version, the output signal resembles a shark fin. With an extension of the rise/fall time by up to 45%, the EMC attenuation at the 11th harmonic wave is above –60 dB. An enormous value for such an easy adaptation of triseand tfall.
