亲爱的Dialog,

Dialog引用的16MHz晶体是7M-16.000MEEQ-T。这个好像脱销了。所以你能建议一个替代的零件号吗?
在AN-B-054 DA14585_Application Hardware Reference Guidelines中,只提到晶体应该具有最大。ESR小于100欧姆。但负载电容、容差、频率稳定性等其他特性呢?双晶片会有什么不同吗?< / p > < p >问好,< br / > sr9213 < / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / da14585 typeof =“skos:概念”属性= " rdfs: label skos:prefLabel" datatype="">DA14585
