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

SoftLevel函數(shù)讓開發(fā)者付出的成本是多少?因?yàn)镾oftLevel功能是LPO, LPOP, HTLPO, WTLPO, UPO, HTLPO- aut和WTLPO- aut系列的SMD硅時(shí)鐘振蕩器的標(biāo)準(zhǔn)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(biāo)準(zhǔn)外殼,因此可以放置在現(xiàn)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(nèi)部工程可以根據(jù)應(yīng)用程序的具體需求為客戶提供最佳建議并編程產(chǎn)品,開發(fā)人員必須準(zhǔn)確地說出他在應(yīng)用程序中可以接受的上升/下降時(shí)間。正是這種編程-延長升/降-實(shí)現(xiàn)諧波泛音衰減。在SMD硅時(shí)鐘振蕩器電路設(shè)計(jì)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(shí)鐘振蕩器的其他優(yōu)勢上述系列的SMD硅時(shí)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(nèi)的任何電源電壓驅(qū)動(例如2.5 VDC±10%,2.8 VDC±10%,3.0 VDC±10%或3.3 VDC±10%)。因此,產(chǎn)品開發(fā)人員只需要為四個(gè)經(jīng)典電源電壓限定一個(gè)振蕩器。這一標(biāo)準(zhǔn)特性為開發(fā)人員節(jié)省了大量用于組件鑒定費(fèi)用,也為供應(yīng)鏈經(jīng)理節(jié)省了大量用于采購、管理和存儲數(shù)量的組件費(fèi)用。大量購買的部件價(jià)格較低,當(dāng)然,SoftLevel功能也可以在2.25 ~ 3.63 VDC的VDD范圍內(nèi)作為標(biāo)準(zhǔn)特性使用。作為另一個(gè)標(biāo)準(zhǔn)功能,SMD硅時(shí)鐘振蕩器具有非常嚴(yán)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(shí)鐘振蕩器的EMC - EMI特性可以通過使用SoftLevel功能簡單地調(diào)整輸出信號的上升和下降而顯著改善,這意味著開發(fā)人員不再需要采取昂貴的措施來改善其應(yīng)用程序的EMC - EMI性能。SMD硅時(shí)鐘振蕩器可以直接放置在現(xiàn)有的PCB布局上。此外,由于VDD范圍為2.25至3.63 VDC,并且標(biāo)準(zhǔn)頻率公差非常嚴(yán)格,因此可以在組件認(rèn)證,采購,管理和存儲方面節(jié)省大量資金。
