TMS370**1DRG4 **价格 中英文资料，**/资料，特性及说明： 
The  transponder  base  station  IC  is  used  to  drive  the  antenna  of  a  TI-RFid  transponder  system,  to  send  data  modulated  on  the  antenna  **,  and  to  detect  and  demodulate  the  response  of  the  transponder.  The  response  of  the  transponder  is  a  FSK  **  (frequency  shift  keyed).  The  high  or  low  bits  are  coded  in  two  different  high-frequency  **s  (134.2  kHz  for  low  bits  and  123  kHz  for  high  bits,  nominal).  The  transponder  induces  these  **s  in  the  antenna  coil  according  an  internally  stored  code.  The  energy  the  transponder  needs  to  send  out  the  data  is  stored  in  a  charge  capacitor  in  the  transponder.  The  antenna  field  charges  this  capacitor  in  a  preceding  charge  phase.  The  IC  has  an  interface  to  an  external  microcontroller.
