10.1 Layout Guidelines

There are no specific layout guidelines because in most cases the DMD is connected using a board-to-board connector to a flex cable. The flex cable provides the interface of data and control signals between the DLPC3430 or DLPC3435 controller and the DLP2010 DMD. For detailed layout guidelines refer to the layout design files.

Layout guidelines for the flex cable interface with DMD are:

  • Match lengths for the LS_WDATA and LS_CLK signals.
  • Minimize vias, layer changes, and turns for the HS bus signals. Refer Figure 10-1.
  • Place a decoupling capacitor (minimum 100-nF) close to VBIAS. See capacitor C4 in Figure 10-2.
  • Place a decoupling capacitor (minimum 100-nF) close to VRST. See capacitor C6 in Figure 10-2.
  • Place a decoupling capacitor (minimum 220-nF) close to VOFS. See capacitor C7 in Figure 10-2.
  • Place the optional decoupling capacitor (minimum between 200-nF and 220-nF) to meet the ripple requirements of the DMD. See capacitor C5 in Figure 10-2.
  • Place a decoupling capacitor (minimum 100-nF) close to VDDI. See capacitor C1 in Figure 10-2.
  • Place a decoupling capacitor (minimum 100-nF) close to both groups of VDD pins, for a total of 200 nF for VDD. See capacitors C2 and C3 in Figure 10-2.
