Cardinal晶振基于创新的IC技术——下一代时钟——提供高度多样化的SMD硅时钟振荡器,具有软电平输出信号。

SoftLevel函数让开发者付出的成本是多少?因为SoftLevel功能是LPO, LPOP, HTLPO, WTLPO, UPO, HTLPO- aut和WTLPO- aut系列的SMD硅时钟振荡器的标准特性(AUT = AEC-Q100中定义的汽车),答案是没有。此外,这些振荡器系列还提供尺寸为7 mm x 5 mm, 5 mm x 3.2 mm, 3.2 mm x 2.5 mm, 2.5 mm x 2.0 mm和2.0 mm x 1.6 mm的标准外壳,因此可以放置在现有的PCB布局上,作为石英振荡器的直接替代品。因此,因此,Cardinal晶振的内部工程可以根据应用程序的具体需求为客户提供最佳建议并编程产品,开发人员必须准确地说出他在应用程序中可以接受的上升/下降时间。正是这种编程-延长升/降-实现谐波泛音衰减。在SMD硅时钟振荡器电路设计中,Cardinal晶振的专家建议在电源电压和接地引脚之间使用0.1 μF的去耦电容。这大大减少了电源电压的影响。。
图3:EMC–EMI降低与长期的关系
SMD硅时钟振荡器的其他优势上述系列的SMD硅时钟振荡器也可用于2.25至3.63 VDC的电源电压范围。振荡器可以由该VDD范围内的任何电源电压驱动(例如2.5 VDC±10%,2.8 VDC±10%,3.0 VDC±10%或3.3 VDC±10%)。因此,产品开发人员只需要为四个经典电源电压限定一个振荡器。这一标准特性为开发人员节省了大量用于组件鉴定费用,也为供应链经理节省了大量用于采购、管理和存储数量的组件费用。大量购买的部件价格较低,当然,SoftLevel功能也可以在2.25 ~ 3.63 VDC的VDD范围内作为标准特性使用。作为另一个标准功能,SMD硅时钟振荡器具有非常严格的频率公差,例如±20 ppm @?40/85°C,±30 ppm @?40/105°C和±50 ppm @?40/125°C。自然,AEC - Q200兼容的振荡器(HTLPO-AUT和WTLPO-AUT)也具有上述所有功能。
SoftLevel功能改善了EMC - EMI特性
SMD硅时钟振荡器的EMC - EMI特性可以通过使用SoftLevel功能简单地调整输出信号的上升和下降而显著改善,这意味着开发人员不再需要采取昂贵的措施来改善其应用程序的EMC - EMI性能。SMD硅时钟振荡器可以直接放置在现有的PCB布局上。此外,由于VDD范围为2.25至3.63 VDC,并且标准频率公差非常严格,因此可以在组件认证,采购,管理和存储方面节省大量资金。
