10 Layout

10.1 Layout Guidelines

There are no specific layout guidelines for the DMD as typically DMD is connected using a board to board

connector to a flex cable. Flex cable provides the interface of data and control signals between the DLPC3478

controller and the 7212-313BK DMD. For detailed layout guidelines refer to the layout design files. Some layout

guideline 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.

• Minimum of two 100-nF decoupling capacitor close to VBIAS. Capacitor C6 and C7 in Figure 10-1.

• Minimum of two 100-nF decoupling capacitor close to VRST. Capacitor C9 and C8 in Figure 10-1.

• Minimum of two 220-nF decoupling capacitor close to VOFS. Capacitor C5 and C4 in Figure 10-1.

• Minimum of four 100-nF decoupling capacitor close to VDDI and VDD. Capacitor C1, C2, C3 and C10 in

Figure 10-1.
