有源晶振的频率问题

来源：百度知道 编辑：UC知道 时间：2024/05/24 11:45:57
我想要个175KHz的时钟频率，问了周围卖晶振的都没有，只有靠分频分下来得到175KHz的，可我算了几个可以分的频率，例如1.75MHz/1.925MHz/2.1MHz/2.275MHz/2.45MHz/2.625MHz/2.8MHz/等等的，又去问了下，都没现成的，应为我就用几个，数量不多，我该怎么办啊，高手请教教我，不胜感激。。。。

常用频率:49S晶振,49US,ZTT 4.00mg,DAY,DY,1.8432MHz,18.432MHZ,25MHZ,4 MHZ,12 MHZ,16 MHZ,13 MHZ,21.47727 MHZ,33.8688 MHZ,3.6864 MHZ,10.245 MHZ,14.7456 MHZ,7.9296875 MHZ,24.576 MHZ,7.2 MHZ,22.1184 MHZ,21.504 MHZ,1.8432 MHZ,13.25 MHZ,24 MHZ,2 MHZ,9.8304 MHZ,20.945 MHZ,9.216 MHZ,14.31818 MHZ,76.8 MHZ,7.3728 MHZ,11.0592 MHZ,44.545 MHZ,40 MHZ,16.384 MHZ,27 MHZ,26 MHZ,48 MHZ,45 MHZ,90 MHZ,130 MHZ,112.32 MHZ,130 MHZ,45.1 MHZ,110.52 MHZ,21.4 MHZ,106.95 MHZ,128.45 MHZ,21.4 MHZ,38.85 MHZ,70 MHZ,45.1 MHZ,26.050 MHZ,8.192 MHZ,44 MHZ,15.36 MHZ,20 MHZ,125 MHZ,25 MHZ,50 MHZ,27 MHZ,65 MHZ,17.734475 MHZ,100 MHZ,32.768 KHZ,31.5 MHZ,29.5 MHZ,56 MHZ,12.288 MHZ,18.432 MHZ,33.333 MHZ,26.975 MHZ,27.145 MHZ,75 MHZ,153.6 MHZ,150 MHZ,455 KHZ,4.91 MHZ,6 MHZ,16.9344 MHZ,10 MHZ,3.64 MHZ,4.1952 MHZ,30 MHZ,8.38 MHZ,4.09 MHZ,16.8 MHZ,4.25 MHZ,9.83 MHZ,33.8688 MHZ,10.7 MHZ,10.8 MHZ,32 MHZ,5 MHZ,14 MHZ,17.28 MHZ,2.68 MHZ,3 MHZ,12.5 MHZ,3.2 MHZ,465 MHZ,446 MHZ,1960 MHZ,433.92 MHZ,225 MHZ,1842 MHZ.5 MHZ,942.5 MHZ,243.5 MHZ,85.
