Cardinal晶振基于創新的IC技術——下一代時鐘——提供高度多樣化的SMD硅時鐘振蕩器，具有軟電平輸出信號。

SoftLevel函數讓開發者付出的成本是多少?因為SoftLevel功能是LPO, LPOP, HTLPO, WTLPO, UPO, HTLPO- aut和WTLPO- aut系列的SMD硅時鐘振蕩器的標準特性(AUT = AEC-Q100中定義的汽車)，答案是沒有。此外，這些振蕩器系列還提供尺寸為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的標準外殼，因此可以放置在現有的PCB布局上，作為石英振蕩器的直接替代品。因此，因此，Cardinal晶振的內部工程可以根據應用程序的具體需求為客戶提供最佳建議并編程產品，開發人員必須準確地說出他在應用程序中可以接受的上升/下降時間。正是這種編程-延長升/降-實現諧波泛音衰減。在SMD硅時鐘振蕩器電路設計中，Cardinal晶振的專家建議在電源電壓和接地引腳之間使用0.1 μF的去耦電容。這大大減少了電源電壓的影響。。

SMD硅時鐘振蕩器的其他優勢上述系列的SMD硅時鐘振蕩器也可用于2.25至3.63 VDC的電源電壓范圍。振蕩器可以由該VDD范圍內的任何電源電壓驅動(例如2.5 VDC±10%，2.8 VDC±10%，3.0 VDC±10%或3.3 VDC±10%)。因此，產品開發人員只需要為四個經典電源電壓限定一個振蕩器。這一標準特性為開發人員節省了大量用于組件鑒定費用，也為供應鏈經理節省了大量用于采購、管理和存儲數量的組件費用。大量購買的部件價格較低，當然，SoftLevel功能也可以在2.25 ~ 3.63 VDC的VDD范圍內作為標準特性使用。作為另一個標準功能，SMD硅時鐘振蕩器具有非常嚴格的頻率公差，例如±20 ppm @?40/85°C，±30 ppm @?40/105°C和±50 ppm @?40/125°C。自然，AEC - Q200兼容的振蕩器(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硅時鐘振蕩器的EMC - EMI特性可以通過使用SoftLevel功能簡單地調整輸出信號的上升和下降而顯著改善，這意味著開發人員不再需要采取昂貴的措施來改善其應用程序的EMC - EMI性能。SMD硅時鐘振蕩器可以直接放置在現有的PCB布局上。此外，由于VDD范圍為2.25至3.63 VDC，并且標準頻率公差非常嚴格，因此可以在組件認證，采購，管理和存儲方面節省大量資金。
