【经验】实战经验告诉你有源晶振在避障传感器中的重要性
【摘要】在验证避障传感器模块可靠性的高温老化实验中发现,当温度升高到65℃以上UART的数据会变成乱码,使得接收端已无法解析收到的数据。笔者采用EPSON的SG-210STF系列48MHz的有源时钟外部的有源晶振给MCU提供时钟,再实验问题得到解决。笔者还用真实的数据验证有源晶振在避障传感器中的重要性。
近年扫地机器人、无人机等智能设备发展迅速,设备的功能越来越智能化,其中避障功能是这类产品智能化的一个主要体现。随之而来,避障传感器的应用也是越来越多。优秀的避障传感器的特点是精度高,稳定可靠。产品的硬件设计简单,但设计的过程中也会遇到意想不到的问题,下面就将我在工作中遇到的问题与各位分享一下。
避障传感器主要由MCU与雷达传感器组成,一般设计成模块类产品。这样的模块方便放置到不同的应用系统中,模块与产品的主控单元通过UART接口进行通讯,为了通讯的稳定性,因此将UART的波特率设置为9600。在设计之初由于需要控制体积和成本,所以采用了EFM8BB2这款MCU,其内部自带的振荡器作为时钟源,模块设计很顺利。在功能设计实现后为了验证模块的可靠性,开始做高温老化实验。在做高温老化实验时出现问题,当恒温箱的温度上升到65℃时,UART的数据开始出现乱码,当温度继续升高,UART的数据全变乱码,接收端已无法解析收到的数据。
是什么原因引起的呢?由于系统并没有死机也没有复位,初步判断应该是振荡器的频率在高温时改变了,所以UART的波特率随之改变而引起的。
为了解决这个问题,我们随后使用外部的有源晶振给MCU提供时钟。此有源晶振我们选择的是Epson的SG-210STF系列48MHz的有源时钟,经过再次的高温老化测试,恒温箱的温度上升到80℃时UART的通讯仍正常。因此问题得到圆满解决。
一颗小晶振解决大问题!实际的问题是我们判断原因引起的吗?下面我们用数据说话。
首先我们要了解,对于这样的数字系统,时钟的初始精度与温度系数是关键的参数。同时,对于UART通讯来说,波特率要严格控制在4%以内,这样才可以保证通讯的稳定可靠。
我们先查一下EFM8BB2 MCU内部晶振的参数,内部高频振荡器的初始频率为48.25MHz~49.75MHz,温度系数为45ppm/℃,MCU的UART的波特率的计算公式如下:
BAUDRATE=SYSCLK/(12*2*(256-TH1))
使用配置软件配置出来的SYSCLK=48MHz,TH1=0x30,这时理论计算的波特率为9600。当温度上升到65℃时,内部振荡器的频率可以按下面的公式计算:
49.75MHz+49.75MHz*65℃*45ppm/℃=49895518Hz
将此频率代入上面的波特率计算公式,可得出此时的实际波特率为9995,误差为4.12%,波特率的误差偏大一些。
下面我们再看一下Epson有源晶振SG-210STF的电气参数。这款晶振的主频为48MHz,初始误差为50ppm,在-40℃~85℃的温度内的误差不超过15ppm。我们按最坏的情况计算在65℃以上时晶振的输出频率为:48MHz+48MHz*50ppm+(48MHz+48MHz*50ppm)*15ppm=48003120Hz
将该频率代入前面的波特率的公式,可以得出波特率为9616,误差为0.2%。远低于4%误差率的要求,完全可以保证在高温下稳定的工作。
从上面可以总结出,使用Epson的有源晶振SG-210STF作为系统的时钟源可以保证整体产品的稳定性,提高系统的可靠性,同时也能大幅缩短研发周期。另建议,在设计对时序要求严格的产品时,千万勿因成本考虑而节省外部的晶振,很可能因小失大。小晶振,解决大问题!

某客户在设计800G硅光模块产品时,由于模块整体封装较小,客户想使用单层板来完成所有的器件设计,原方案搭配DSP使用的有源晶振选用的3225封装,封装太大放不下,所有需要使用更小封装的产品,本文推荐EPSON超小封装有源晶振X1G006111000099。

【应用】EPSON小封装有源晶振X1G005941000215导入相干光模块产品设计,工作温度-40℃到105℃
某客户在设计一款相干光模块产品时,由于布板面积比较紧张,搭配DSP使用需要选用小封装的有源晶振,参数要求2.5V供电、频点为156.25MHz、差分输出、温度范围-40~85℃、2520封装有源晶振,结合客户的需求,本文推荐EPSON 2520封装产品X1G005941000215。

选型EPSON的有源晶振产品需要了解哪些参数?
与无缘晶体这四个参数要求是一样的:工作频点,封装要求,频偏要求,温度要求,另外有源晶振还需要供电电压要求,不需要负载电容,因为有源晶振是IC+晶体,所以内部的有起振电路和负载电容等。

一键车窗升降器控制模块,需要用到频率为24Mhz、高精度、小封装的晶体振荡器,有合适的晶体振荡器推荐吗?
推荐使用型号FA-118T,频率为24Mhz,频率稳定度为10ppm的晶体振荡器。
