Read Operation
Once the IC detects the incoming RF, the IC repetively
reads out the code data as long as the RF signal is applied.
The transition from the last bit to bit 1 of the next
sequence occurs without interruption. Data is transmitted
by alternating damping of the incoming RF via a load.
Different kinds of modulation and bitrates are optionally
available.

For internal power supply, an on-chip bridge rectifier is
used which consists of two diodes and two n-channel
transistors. A Zener diode, which protects the circuit

Damping Load
Incoming RF will be damped by the power consumption
