HCS473
Table 7-5 timing values are compensated only for
HCS473 internal filter delays. The transponder reader
designer must compensate communication timing
accordingly for the cumulative antenna delays.
Use LF Demodulator mode to see the effects of the
internal filters and the LC antennae, Section 3.2.1.2.
It must be clearly understood that the HCS473 core
does not see the LF field immediately upon the base
station turning it on, nor does it immediately detect its
removal. If the internal analog delay and cumulative
antenna delays are greater than a given low time, the
HCS473 will obviously never “see” the low.
