概览

A5191HRT 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。该调制解调器结合一些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。A5191HRT 可与 SYM20C15 实现引脚兼容。参见“引脚说明”和“功能说明”部分了解与 SYM20C15 之间引脚兼容性的详细信息。A5191HRT 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禁用，反之亦然。这提供了 HART 通信中使用的半工运行。

  • Highway Addressable Remote Transducer (HART) field instruments and masters
  • Instrumentation terminals and measurement devices
  • Low power
  • Bell 202 shift frequencies of 1200 Hz and 2200 Hz
  • Single-chip, half-duplex 1200 bits per second FSK modem
