DC AND AC PARAMETERS

This section summarizes the operating and mea-

surement conditions, and the DC and AC charac-

teristics of the device. The parameters in the DC

and AC Characteristic tables that follow are de-

rived from tests performed under the Measure-

ment Conditions summarized in the relevant

tables. Designers should check that the operating

conditions in their circuit match the measurement

conditions when relying on the quoted parame-

ters.

Table 12. Operating Conditions

Figure 39. LRI64 Synchronous Timing, Transmit and Receive

Figure 39. shows an ASK modulated signal, from

the VCD to the LRI64. The test condition for the

AC/DC parameters are:

–

Close coupling condition with tester antenna

(1mm)

–

Gives LRI64 performance on tag antenna
