Functional Description
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.
Rectifier
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
against overvoltage on the coil inputs, and a smoothing
capacitor for the internal supply are also provided.
Damping Load
Incoming RF will be damped by the power consumption
of the IC itself and by an internal load, which is controlled
by the modulator. The loads are p-channel transistors
connected between VDD and the coil inputs. The layout
includes metal mask options for the load circuit:
single-side, double-side and alternate-side modulation.
Modulator
One of four methods of modulation can be selected by
fuses. The timing diagram is shown in figure 5.
FSK
Logical “1” and “0” are distinguished via different
frequencies of damping. The frequency for “1” is the RF
divided by 10, a “0” divides by 8.
