9.1 Layout Guidelines

The DMD is connected to a PCB or a flex circuit using an interposer. For additional layout guidelines regarding length matching, impedance, and so on. see the DLPC3421 controller data sheet. For a detailed layout example refer to the layout design files. Some layout guidelines for routing to the DMD are:

  • Match lengths for the LS_WDATA and LS_CLK signals.
  • Minimize vias, layer changes, and turns for the HS bus signals. Refer to Figure 9-1.
  • Minimum of two 100nF (25V) capacitors—one close to VBIAS pin. Capacitors C4 and C8 in Figure 9-1.
  • Minimum of two 100nF (25V) capacitors—one close to each VRST pin. Capacitors C3 and C7 in Figure 9-1.
  • Minimum of two 220nF (25V) capacitors—one close to each VOFS pin. Capacitors C5 and C6 in Figure 9-1.

  • Minimum of four 100nF (6.3V) capacitors—two close to the VDD/VDDI pins on each side of the DMD. Capacitors C1, C2, C9, and C10 in the layout example.
