Word Distance
Basic Unit of Pulse Distance
The following number of pulses may be selected by Metal option : N= 8, 12, 16.
Note :
The different dividing ratio for T
O
and t
W
between flash mode and carrier mode is obtained by changing the modulo of a particular di-
vider from divide by 3during flash mode to divide by 4 during carrier mode.This allows the useof a 600kHz ceramicresonator dur-
ing carrier mode to obtain a better noise immunity for thereceiver without a significant change in T
O
and t
W
. For first samples, the
correct divider ration is obtained by a metalmask option. For final parts, this is automatically done togetherwith the selection of
flash-/carrier mode.

Table 3 :
Transmission Mode and Sub-system
Adress Selection.
The sub-system address and the transmission
mode are defined by connectingthe ADRM input
to one or moredriver outputs(DRV0N To DRV6N)
of the key matrix. If more than one driver is con-
nected to ADRM, they must be decoupled by di-
odes.
