Figure 9 Level Lamp Synchronization Mode Timing
Figure 10 Rising Edge Lamp Synchronization Timing
Lamp Lit - LAMPLITZ
The LAMPLITZ signal shall be asserted to the DDP1000 electronics after successful ignition of
the projector lamp. The transition of LAMPLITZ from high to low is used to reset the DDP1000
electronics, so the LAMPLITZ signal must transition from high to low after the lamp ignition EMI
pulse is over to guarantee operation is not affected by the ignition EMI. No DDP1000 electronics
configuration should be attempted until LAMPLITZ is low and stable. When the lamp is disabled the
LAMPLITZ shall be driven high. See Figure 11 for detailed timing on the LAMPLITZ during power
up.
