9.4.1 Data rate and data coding
9.4 Communication signal interface - HITAG µ transponder IC to RWD
The HITAG µ transponder IC accepts the following data rates and encoding schemes:
T
Remark: The slower data rate used during the inventory process allows for improving the
collision detection when several HITAG µ transponder ICs are present in the RWD field,
especially if some HITAG µ transponder ICs are in the near field and others in the far field.
Differential Bi-phase (or FM0 respectively) contains a transition in the center of bit
conversion representing Data ’0’ and no one for Data ’1’. At the beginning of every bit
modulation a level transition must be performed.
