Table 1 : Pulse Train Timing
The following number of pulses may be selected by Metal option : N = 8, 12, 16.
Note : The different dividing ratio for T

Table 3 : Transmission Mode and Sub-system
Adress Selection.
The sub-system address and the transmission
mode are defined by connecting the ADRM input
O= connected to ADRM
blank= not connected to ADRM

vider from divide by 3 during flash mode to divide by 4 during carrier mode. This allows the use of a 600kHz ceramic resonator dur-
ing carrier mode to obtain a better noise immunity for the receiver without a significant change in T
correct divider ration is obtained by a metal mask option. For final parts, this is automatically done together with the selection of
flash-/carrier mode.
