The DLP472TP DMD
connects to a PCB or a flex circuit using an interposer. For additional layout
guidelines regarding length matching and impedance, see the DLPC8445 controller data sheet. For a detailed
layout example, refer to the layout design files. Some layout guidelines for routing
to the DLP472TP DMD are:
- Match lengths for the LS_WDATA and LS_CLK signals, as specified in the DLPC8445 controller data sheet.
- Match lengths for the HS_bus differential signals
as specified in the DLPC8445 controller data
sheet.
- Minimize vias, layer changes, and turns for the HS bus signals. Refer to Figure 9-1.
- Supply capacitance needs can vary per design. Refer to the layout design file for a general guideline. Supplies need to be verified on the design to ensure all supplies are operating in the recommended operating range at the DMD.
