Multiple Lamp Sync
The figure 3 shows the sync signals (PHA_SYNC and
RMP_RST) timing relationship to Gate signal AOUT,
for the master module. AOUT and PHA_SYNC running
at the same frequency and RMP_RST signal has the
twice frequency.

Strike Mode
Every IC includes a separate strike controller that operates
from the primary oscillator; therefore the strike controller is
independent of the sync signals. The following oscilloscope
waveform picture is taken when the master module is on
striking mode and the salves are on running mode.

Output Drivers
The figure 4 shows the gate signals of the modules,
which are operating, in running mode during digital
dimming with 95% duty cycle. As shown all signals are
synchronized. The difference between each signal’s duty
cycles is because each lamp has an independent control
loop.
