车规级晶振具备哪些特性?
各类汽车上的车载设备使用的晶振对工作温度(一般要求105℃或125℃高温晶振)、抗震性等有严苛要求,需要满足AEC-Q100/AEC-Q200等相关技术标准,因此也被称为车规级晶振。车规级晶振分为无源晶振和有源晶振两大类,车规晶振中最常见的温补晶振TCXO属于有源晶振的一种。
车规级高精度温补晶振TCXO具体电气参数如下:
标称频率范围Nominal Frequency Range:13MHz~55MHz
额定电压Supply Voltage:典型值为1.8V/典型值为3.3V
工作温度范围Operating Temperature Range::±0.5×10-6Max(-40℃至~105℃或125℃)
特点优势Electrical Characteristics and Advantages:低噪音,105℃或125℃过高温,符合AEC-Q100
车规级高精度温补晶振TCXO主要应用领域:
GPS:汽车导航卫星系统
TCU:汽车远程信息处理控制单元
DSRC:汽车专用短程通信
Autonomous smart cars:智能汽车与自动驾驶技术
