DLPS024G August 2012 – February 2020 DLPC410
PRODUCTION DATA.
Now that the DMD ID has been assessed by the DLPC410, the Controller will finish the DLPA200 initialization to set the DLPA200 voltages to their final operating settings for the specific connected DMD. The DLPC410 outputs DAD_A_SCPEN (pin AE3) and DAD_B_SCPEN (pin AB19) will assert indicating that the DLPC410 is ready to communicate with the DLPA200 devices. Signaling should be seen on SCPCLK (pin AB15), SCPDO (pin AA15 - SCP data output from the DLPC410) and SCPDI (pin AA15 - SCP data input to the DLPC410). During layout, ensure that the direction of the SCP data input and output signals are connected correctly.
When DLPA200 initialization is complete, check VBIAS, VRESET, and VOFFSET voltage values on both DLPA200 devices and compare against the DLPA200 data sheet specification and the DMD data sheet specification for the DMD connected to the DLPC410.
