移动调频多路广播解调器(DARC)接收器

添加至我的收藏

概览

LC72711LW 是一个数据解调器集成电路,用于接收以 DARC 格式进行移动接收的 FM 多路广播。该集成电路包括一个片上带通滤波器,用于从 FM 基带信号中提取 DARC 信号。此外,由于该集成电路支持所有 IT-R 建议的 FM 多路复用帧结构(方法A、A、B 和 C),因此它是提供 FM 多路复用接收的全球市场无线电的最佳选择。LC72711LW 支持并行和“计算机控制总线”串行 CPU 接口。

  • Adjustment-free 76 kHz SCF bandpass filter
  • Supports all FM multiplex frame structures under CPU control.
  • MSK delay detection system based on a 1T delay.
  • Error correction function based on a 2T delay (in the MSK detection stage)
  • Digital PLL based clock regeneration function
  • Shift-register 1T and 2T delay circuits
  • Block and frame synchronization detection circuits
  • Functions for setting the number of allowable BIC errors and the number of synchronization protection operations.
  • Error correction using (272, 190) codes
  • Built-in layer 4 CRC code checking circuit
  • On-chip frame memory and memory control circuit for vertical correction
  • 7.2 MHz crystal oscillator circuit
  • Two power saving modes: STNBY and EC STOP
  • Applications can use either a parallel CPU interface (DMA) or a 'computer control bus' serial interface.
  • Supply voltage: 2.7 to 3.6 V
