概览

NCN5193 是一种单芯片 CMOS 调制解调器，用于可寻址远程传感器数据公路 (HART) 现场仪器和主节点。该调制解调器结合几个外部无源部件，可提供满足 HART 物理层要求所需的所有功能，包括调制、解调、接收滤波、载波器检测以及发射信号整形。此外，NCN5193 还有一个集成 DAC，用于实施低 BOM 电流回路从发射器。NCN5193 在每秒 1200 位的速度下使用相位连续移频键控 (FSK)。为了节省电能，在发射运行期间接收电路将被禁用，反之亦然。这提供了用于 HART 通信的半双工运行。

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
