Description
1.8 V supplied by Panda
5 V supplied by TLV62130 (U28) of DLP
LightCrafter 4500
No connect
When high, Panda enables the level shifters, muxes
the RGB signals to DLPC350, and disables TFP401.
When low, RGB signals are muxed to TFP401 and
level shifters to Panda are disabled.
No connect
DLPC350 UART0_RX level-shifted to 1.8 V
No connect
DLPC350 UART0_TX level-shifted to 1.8 V. Outputs
error info from DLPC350.
No connect
DLPC350 TRIG_IN_1 level-shifted to 1.8 V. This
signal advances the pattern during Pattern
Sequence mode.
No connect
DLPC350 TRIG_IN_2 level-shifted to 1.8 V. This
signal is used as a start (rising edge) or stop (falling
edge) during Pattern Sequence mode.
No connect
DLPC350 EXT_POWER_ON level-shifted to 1.8 V.
This signal indicates to OMAP4 the DLPC350 is
powered ON.
No connect
DLPC350 TRIG_OUT_2 level-shifted to 1.8 V.
DLPC350 active high signal to indicate first pattern
in Pattern Sequence mode.
No Connect
DLPC350 TRIG_OUT_2 level-shifted to 1.8 V.
DLPC350 active high pattern exposure signal during
Pattern Sequence mode.
No connect
DLPC350INTI_DONE level-shifted to 1.8 V.
DLPC350 active high pulse signal to indicate system
initialization is complete.
No connect
Signal from OMAP4 to switch the TS3USB221 mux.
When low, driver board USB connector is routed to
DLPC350. When high, OMAP4 drives USB to
DLPC350.
