COMMUNICATIONS SIGNAL FROM LRI64 TO VCD
The ISO15693 standard defines several modes,
for some parameters, to cater for use in different
application requirements and noise environments.
The LRI64 does not support all of these modes,
but supports the single subcarrier mode at the fast
data rate.
Logic 0. A logic 0 starts with 8 pulses of
423.75kHz (fC/32) followed by an unmodulated
period of 18.88µs as shown in Figure 9.
Figure 9. Logic 0, High Data Rate
Load Modulation
The LRI64 is capable of communication to the
VCD via the inductive coupling between the two
antennas. The carrier is loaded, with a subcarrier
with frequency fS, generated by switching a load in
the LRI64.
The amplitude of the variation to the signal, as re-
ceived on the VCD antenna, is at least 10mV,
when measured as described in the test methods
defined in International Standard ISO10373-7.

Subcarrier
The LRI64 supports the one subcarrier modulation
response format. This format is selected by the
VCD using the first bit in the protocol header.
Logic 1. A logic 1 starts with an unmodulated
period of 18.88µs followed by 8 pulses of
423.75kHz (fC/32) as shown in Figure 10.
The frequency, fS, of the subcarrier load modula-
tion is 423.75kHz (=fC/32).
Data Rate
Figure 10. Logic 1, High Data Rate
The LRI64 response uses the high data rate for-
mat (26.48 kbits/s). The selection of the data rate
is made by the VCD using the second bit in the
protocol header.
Bit Representation and Coding using One
Subcarrier, at the High Data Rate
37.76 µs
Data bits are encoded using Manchester coding,
as described in Figure 9. and Figure 10.
