TimerBlox：可重置的低频振荡器

LTC6991是一种硅振荡器，可编程周期范围为1.024毫秒至9.54小时（（29.1µHz至977Hz），LTC6991是TimerBlox®系列通用硅定时装置的组成部分。\n\n一个电阻RSET即可对LTC6991的内部主晶振频率进行编程。输出时钟周期由这个主振荡器和内部分频器NDIV（可编程为八个从1至221的设置）确定。\n\n正常运行时，LTC6991以50%的占空比振荡。提供复位功能以截断脉冲（降低占空比）。也可使用复位引脚来防止输出振荡。\n\n可使用极性功能配置RST和OUT引脚用于有效低电平或有效高电平操作。\n\n • 周期范围：1毫秒至9.5小时 \n\n• 使用1至3个电阻配置 \n\n• 最大频率误差<1.5% \n\n• 输出复位功能 \n\n• 2.25V至5.5V单电源供电 \n\n• 55µA至80µA电源电流\n\n• （2毫秒至9.5小时时钟周期）;
