【应用】国产无源晶体SMCE-3225用于WiFi 6 AP，老化率±3ppm，使用寿命长

时间： 2022-07-26 来源：应达利

技术问答

随着5G商用的加速，WIFI 6市场也迎来了一波需求暴涨。相比之前的版本而言，WIFI 6在很多方面都有优势，具体表现在速率更快，更安全，且更省电。WiFi5最大传输速率为3.5Gbps，而WiFi6最高速率可达9.6Gbps。WiFi5只涉及5Ghz频段，而WiFi6覆盖了2.4、5Ghz两个频段。此外，WiFi 6（无线路由器）设备若需要通过WiFi联盟认证，必须采用WPA 3安全协议，安全性更高。WPA3安全协议安全性进一步提升，可以更好的阻止强力攻击，暴力破解等。WiFi 6引入了TARget Wake Time（TWT）技术，允许设备与无线路由器之间主动规划通信时间，减少无线网络天线使用及信号搜索时间，能够一定程度上减少电量消耗，提升设备续航时间。

晶振在WIFI 6中起到为主控芯片提供时钟的作用。应达利为WIFI 6应用提供的晶振频点从16MHz，到96Mhz。其中常用的有40MHz、50MHz、96MHz等。

应达利的无源晶体 SMCE-3225 20MHZ（料号5YAA20000101SF70Q2），通过博通芯片IC:BCM43217KMLG认证，可完美应用于WiFi 6 AP。5YAA20000101SF70Q2具有高精度、高稳定性的特点，安全性高，老化率±3ppm，使用寿命长，封装尺寸3.2mmX2.5mm，有利于节省空间。

应达利晶振SMCE-3225 为表贴缝焊式陶瓷封装晶体谐振器，其尺寸小巧，符合RoHS标准且无铅，具备高可靠性、频率范围广的优质特性，还可广泛应用于安防行业、汽车电子、工业应用、通讯应用、消费电子、医疗应用等。

规格图1

石英晶振能够提供稳定输出是一项十分重要的要求。SMCE-3225的工作温度范围是-40 ˚C ~ +125˚C，储存温度范围是-55°C ~ +125°C。
