20.2 Carrier Frequency
The carrier frequency and the pulse of data are calculated
by below formula. The the lengths of carrier frequency and
pulse of data are shown in Figure 20-3.
tH = source clock(RMR[5:4]) × CFHS
tL = source clock(RMR[5:4]) × CFHS
fC (Carrier Frequency) = 1/(tH+tL)
t
DH = source clock(RMR[2:0]) × RDHR
tDL = source clock(RMR[2:0]) × RDLR
