Vbias SUPPLY FOR DMD POND/BORDER MIRRORS
im going over the datasheets and noticed for the DLPA200 - the following statement:
Provides a VBIAS voltage level, used by theDMD to control the array border mirrors
but in the datasheet for the DAD2000 - as on my Discovery 4000 kit it states:
VBIAS is supplied directly to the DMD to bias the border mirrors to the off state -
i cant see how this was acheived on the discovery 4000 schematics either....
I had been previously informed that the DAD200 and DLPA200 were identical in operation - hence i should be able to drive 0.5" or 0.7" dmd for the same device - Disregarding different controller chips that is.
Can i have quick clarification as to whether there is an extra connection to supply the POM's with this Bias Voltage? - our design will be using the DLPA200 device and 0.7" DMD - 1076N732.
The DLPA200 is a drop in replacement for DAD2000, so that any device that the DAD2000 can drive, can be driven with the DLPA200.
Actually the Pond of Mirrors (POM) is driven by the MBRESET(15:0) lines and experience mirror resets just like the active array. The only difference is that he border pixels are permanently loaded to the "0" state and cannot be addressed, so that the only state they can have is "0".
